Clearly you don't understand the issue. Apple is not tracking you since they do not collect this data. Rather your phone is generating a local cache of nearby cell towers and wifi hotspots. This benefits you by making your phones GPS function faster, more accurately and with less battery.
The issue is that the cache is not properly protected and could be used to infer some generalized information about roughly where your phone has been. This data is only accessible by somebody with direct access to your phone, or you phones backup files.
Why do people like that the data on their phones is encrypted and can be remotely wiped? Because it all too likely that something on your phone should not fall into somebody else's hand.
Enabling encryption of the phone by default is just taking reasonable precautions. Creating this data log (by which I mean not deleting any but the most recent entries) is not taking what would be a very reasonable precaution.
I always wondered why the option to encrypt the iPhone backup was there. What data would be on my iPhone but not on my computer (e-mails, browsing history, all sorts of passwords are generally both on my iPhone and my computer). Now I know of one reason, that Apple (or a third-party app) might without my knowledge create databases relating to my phone usage that are more critical than the rest of the data on my computer.
The point is that I would have assumed that any app or part of the OS creating a database would be open and transparent about it.

Key word being DESKTOPS.
MP machines were server based long before they were included in desktops. I'd like to see where people had dual Xeon based DESKTOPS 'cause I've never seen it. It's not impossible but it's also not a good cost-based answer either. :p
I've known many people with multi-processor machines on their desktop, with a variety of processor families -- including Intel -- going way back over the best part of a decade. If your requirements include applications that can make use of it, it can make sense. Time is money and all that.
One market I'm aware of is the fluid dynamics market, which pretty much eats all the processor time you can throw at it.
I even had an x86 dual CPU machine at home back in 1999... I still have it, it's just not that fast any more...
Of course, these days everyone and his dog has dual-core, pretty much...

Normally I would argue that the customer doesn't have a right to a lot of things. But in this case - if you bought a device and it is tracking you (I'm not saying it is or it isn't) - the customer does have a right to know.
This (sort of) reminds me of how now your are legally allowed to get a free credit report once a year to determine whether or not it's correct. Companies used to make a fortune charging for something that people, inherently had the right to know.
If people learn to read they would know.... Thank to wprowe

I don't give a rat's A** about Santa Rosa. What I do give a Rat's A** about is that Easy Access HD Bay. The ability to have multiple 160 GB HDs standing by for different field purposes can make for revolutionary work flow procedures.
Exactly!! I did swap my MBP HD from 100GB (Seagate 5400.2) to 160GB (Seagate 5400.3) and almost cracked the top cover, not to mention destroyed the warranty (which I don't mind anyway). Its really funny that we can easily swap HD in MB but not in MBP. I hope they fix this in next release instead of silly Merom updates.

So if Im getting this right....I bring my 3GS to Radio Shack on the 15th to preorder the iphone 4 and then I have to turn in my old phone in order to get the buy back gift card? But then I would be without a phone for over a week? My local Radio Shack said I could get $256 for my 3gs. But if I read right that price could go down the closer it gets to the ip4 launch?
Thanks

Blackberry playbook = The IPad 2 killer - you heard it here first.
Look at the specs, their greater or equal to the iPad 2 with the exception of battery life.
Except for the battery life. Ha, ha . . . yeah, that's not important at all in a mobile device. You get your 10.1 inch "point and shoot" camera, I'll take the battery for a handheld portable computer. Haven't heard a lot of concern over all the laptops without a rear-facing camera. It's funny how critical it is for the iPad though, and what an important comparison it is to many people.

At least 100k people know what its like to have a really FUNCTIONAL Tablet.
please tell me! what defines a functional tablet
I'd assume that that would be user specific for their needs. Different strokes for different folks and all.

For most people the ipad is more useful than the air anyway imo. Yes i owned an air, the ipad 1, and now the ipad 2 and the air was just a watered down macbook pro more than the ipad is a scaled up ipod touch
Alas, there are some things that the curated app store will never be able to supply. Case in point: a pokerstars or fulltilt client. And if the ipad's Safari can't do java or flash or allow me to run the applications of my choosing, then it's not sufficiently open for my needs.

What you and every other non-informed are missing is the Xoom lack of apps is a not really a con for 2 reason.
1. Unlike iOS, ALL APPS, in the android market scale to fit the 1280x800 screen. No x1 or x2 crap. So I can still ENJOY my facebooke app on a larger screen. Nothing is lost. "optimized for tablets" gives me the same information just with a different interface. So long has my twitter app or facebooke or squeezebox app scale so i can see all. I am a happy camper.
2. Unlike iOS i would argue that the xoom needs LESS apps to do functions that take iOS 3 or 4 apps to do. I dont need goodreader or the like because I have a native file system. I dont need skyfire because i have flash. I dont need to open in here, open in there. Every app can have access to each other...
1. Have you seen how those apps "scale" on XOOM? That doesn't make them optimized for tablets, just fit more screen space and even that doesn't work that well.
2. Bull.

What is the obsession with back-lit keys?
Do you actually look at the keyboard when you're typing?
Nope, I touch type.
BUT, when I'm just lying around on the couch websurfing or reading something on the screen, then my hand is on the mouse pad, and when I need to reach up to hit a command-key or type a lazy couple of words into chat, or type in a password, or etc. then I LOVE the backlit keyboard. It's amazing how often it comes in handy.
Sure, I can get along without it - my current MBP is the first computer I've had with it. But do I WANT to get along without it? NooOOOooo!
But it's not because I have to look at the keys while normally typing.

Mine is installing right now too. The install process is rather long and tedious, but I can't wait to try out the Top Gear track first if I can. I wonder how many petrolheads are going to do that first? :D
Idk how long it took, i put the disc in and got lunch. When i came back it was done :)
So far i'm loving it. The physics are a huge step forward from any other console sim, the AI is much better than GT4 (though still not great), and the xp system works really well. I agree with the reviews though, its an incredible sim but lacks in other areas, like leaderboards and whatnot. Luckily i bought the game simply to drive and collect cars, so its pretty perfect for me.

The only reason I see Apple going all Woodcrest is to justify their high markups , while insulting you Mac Loyalist on price they also offer you less performance for your money.
Look here at the current woody pricing at Newegg
http://www.newegg.com/Product/ProductList.asp?Submit=ENE&N=50001157+2010340343+1050922423&Subcategory=343&description=&srchInDesc=&minPrice=&maxPrice=
So apple is going to charge you guys $1799 for a Desktop with a 2.0ghz CPU , when everyone else will charge $1199 for a Conroe E6600 2.4ghz based desktop.
This is not looking good apple.
You can be quiet now. Go on Dell's medium/large business site, which is the *only* section you can find the Woodcrests in single/dual configs (HP doesn't have theirs out yet), and configure one with a decent video card, 250GB HD, no monitor, and any of the rumored processor configurations (which I think some are not correct), a DL DVD+/-RW burner, and optical mouse and you tell ME how much it costs.

Problem is, its still Final Cut and will still suck at managing media.I work in all three worlds with NLE (Avid, Apple & Adobe). If your know what your doing, then Media Management should be as easy as pie. Now do you have something specific that irks you about FCP? For starters I instruct at a local college in the evenings. I first burn it in my students heads that they need to use an separate drive for this app.

I've been wanting to say this for a very long time. Google's OS has no advantage over iOS. You could even say it has a disadvantage. Having to create a vanilla code base that needs to function on multiple pieces of hardware is complex, more complexity creates weaker system.
But here's my point. The ONLY ONLY reason why Android market share is anywhere near what it is today is because of the Buy One Get One options at most phone retailers. iOS has NEVER done that and hopefully never will. If you didn't care about the phone or service but needed two "Newer Smart Phones" one for you and one for your wife, why not go with the "Blah Blah" model from Verizon where if I buy one today I get the second for free (two year agreement and activation fees required).
Market share means nothing. This platform is doomed unless Google reins it in and get control over it. If they do, providers will be less willing to work with them, if they don't, by by Android.
My Two Cents.

Iphone are sold BOGO and even just free on contract over in other countries.
Android has quite a few advantages over iOS. And as it stands right now, android is still as "open" as it was 1 minutes before this article got posted

2/22 to Present: Apps? Who needs Apps as long as you have a robust UI?
3. Open
2007 to Today: Apple is a walled garden that only stupid lemmings use.
Today going forward: Controlling the OS is necessary and good for the consumer.

You could also add to it:

Yes, absolutely:
Enhanced 64-bit Support
Leopard delivers 64-bit power in one, universal OS. Now Cocoa and Carbon application frameworks, as well as graphics, scripting, and the rest of the system are all 64-bit. Leopard delivers 64-bit power to both Intel- and PowerPC-based Macs, so you don�t have to install separate applications for different machines. There�s only one version of Mac OS X, so you don�t need to maintain separate operating systems for different uses.
Bridge the Generation Gap
Now that the entire operating system is 64-bit, you can take full advantage of the Xeon chip in Mac Pro and Xserve. You get more processing power at up to 3.0GHz, without limiting your programs to command-line applications, servers, and computation engines. From G3 to Xeon, from MacBook to Xserve, there is just one Leopard.
Wait. Does this mean that the Leopard doesn't support current MBP or MB? the ones that use 32 bit Yonah based Core Duo CPU.

I disagree. Using ATX power supplies is a stupid idea. I am sure Apple uses higher quality power supplies than you would pick up at your local CompUSA.
If they allow this there will be a lot of dead Macs, from power supplies whose rails aren't strong enough.
Not to mention those who buy the 400W model because it is only 20 bucks and drastically underpower there Mac.
This would cause too many problems. Keep it proprietary IMO.
Well I wouldnt worry about that in the case of a mac. Only people who are really going to replace there PSU are going to be people who know something about computers. A lot of people replace there ram. PSU are not upgraded very offen if ever at all.
Also the people who do replace PSU most of them know dont cheap out on them. Among home builder comminty a thing most agree on is NEVER cheap out on a PSU. Go name brand. Reason being is why would you build a 1k system and then risk it all with a cheap PSU (rule can be cut if pretty much using dirt cheap parts to begin with and trying to go as cheaply as possible (less than 500 and in old spare parts). My own PC rig using an Antec True Power PSU in it (that i pick up from compUSA oddly enough).
I think going ATX is a good thing because it means Apple is going to be using more standardized parts so it will be cheaper for apple to get them.

First of all, you assume that it is possible to make "one big core equal in processing power to the 8 cores". I don't think it is possible to do this (at least not with the x86 architecture using today's technology.)
But assuming such a chip exists, the answer depends on what kind of efficiency you're thinking of.
If you mean computational efficiency (meaning the most useful processing per clock-tick), then a single big core will do better. This is because single-threaded apps will be able to use the full power (whereas multiple threads are needed to take advantagte of multiple cores.) Also, the operating system can get rid of the overhead that is needed to keep software running on the multiple cores from stepping on each other.
If you mean energy efficiency (amount of processing per watt of electricity consumed), then it could go either way, depending on how the chips are made. But given today's manufacturing processes and the non-linear power curve that we see as clock speeds are increased, the multiple-core solution will almost definitely use less power.
I remember hearing about how it is possible to make multiple cores act like one (Idon't remember where I heard this). Anyways, whether 8 cores acting separately or together like 1 big processor has an advantage depends on the program you use. If the program is multi-threaded, then the cores acting separately might have the advantage while single threaded apps will have an advantage if the cores are acting like one. However, many apps today won't see that much improvement either way (like a simple calculator, or solitare and word processing).
