I think Reverse Hyperthreading will have to be processor-bound, like Hyperthreading. Intel has its mitosis project, so let's hope that works out well!
There is no such thing as "Reverse Hyperthreading". This has been completely debunked.

The trouble is .. I find the TDP numbers for Sandy Bridge very misleading. For example the previous i7 2.66Ghz dual core had a TDP of 35W and the current i7 2.2Ghz quad core has a TDP of 45W. Theoretically, it should only use 10W more when doing CPU intensive task, but according to anandtech who measured the task, the i7 Sandy Bridge Quad core was using almost 40W more when running cinebench.
http://www.anandtech.com/show/4205/the-macbook-pro-review-13-and-15-inch-2011-brings-sandy-bridge/14
It just doesn't make any sense. Going by those figures, if the i7 dual core was 35W, the i7 Sandy Bridge quad core would be around 70W.
Not sure how this relates to potential MacBook Air Sandy Bridge processors, but keep in mind.. there must be a reason why Samsung went for the ULV processor in their 13" laptop instead of the LV one.
CPU isn't the only thing that changed. AMD 6750M (~30W) has higher TDP than NVidia GT 330M (~23W). I had to put ~ because their TDPs are not officially stated by AMD or NVidia so it's just based on previous GPUs and their TDPs. The point is that AMD 6750M has higher TDP.
There is also another thing. TDP is not the maximum power draw. Maximum power dissipation is usually 20-30% more than the actual TDP. While MPD is rarely achieved as it requires maximum voltage and temperature, it can (nearly) be achieved with heavy benchmarking applications.
For example, the combined TDP from quad core SB and AMD 6750M is 75W. If we use 20% extra as the MPD, that is 90W, just from the CPU and GPU! Of course those parts are not using 90W in that test because things like screen, HD, RAM etc need power too. As the MPD is usually in percents, it can explain why the difference is so big in watts.
40W sounds a bit too much to explain with MPD though. IIRC the GT 330M is underclocked but I'm not 100% sure. You have a valid point that the SBs may be using more power than their predecessors. To make this more accurate, we should compare them with C2Ds though ;)
I guess we will have to wait and see, but an ULV in 13" would be more than a disappointment.

This is a lie
Keeping a database of our general location is logging our location. :mad:
No it isn't. They say they are not logging your location. This is correct. If it were incorrect, they would be keeping a database of your phone's exact GPS location. Instead, as they state, they are keeping a cache of the cell towers and wifi hotspots in order to aid the A-GPS system. So, no, they are not logging your (and by your, I mean an identifiable log) exact locations and beaming it home to watch you like big brother.
As has been stated a million times, there is a likely bug that wasn't culling the cache. It was also a dumb oversight to backup the file and to do so unencrypted.
The overlord hyperbole is really silly.

And I guess it works both ways. If the iPad is a Honda, the Xoom is a Hyundai, or more and more of late, a Kia.
Just enjoy a device for what it is... these child-like torts are silly. Both are nice. The only true differentiating factor is the AppStore right now.
What bothers me is people think because an iPad sells more it is superior, unless you made the iPad or work at Apple I don't see how that makes sense. Also most people on here have never even played with a XOOM.
I own both an iPad2 (my wife's technically) and my XOOM. I had an iPad1 since launch until I sold it for a XOOM. For me, Apps are lacking on XOOM but it's made up for with the true tablet OS and excellent first party apps.
Find me a better GMail/Email, Maps, Browser on the iPad and other stuff you will actually use most often and I'll sell my XOOM. Since I've had my XOOM, I haven't touched the iPad2. Everytime I pick it up I miss using the XOOM.

I wish they would leave it on and let me use it. I consider it a feature. It would help me track hours at job sites automatically for billing. I thought of writing an app just for that.
That's an interesting idea.
I actually like Apple's response. I do think that being able to turn OFF the feature was an oversight on their part but I do wish there was a way to leave it on. I'd actually welcome a way to import that database into Aperture and use it geotag my photos. Yes, there are apps to do that but I have an iPhone 3G and so backgrounding those apps isn't really possible.

The only problem is that Apple will have to be on the ball with upgrades so as not to loose the speed war against other intel machines (running Windows unfortunately) but we will all want the latest and fastest processors in the line-up even if we are not in the market for a new computer...

They are comparing a 2 generations old G5 (Dual 2,5) versus a new Intel (Quad 2,6) which is not even the fastest out there. What kind of comparison is that?
If you want to know what is the fastest Mac, the comparison is no good. If you want to know whether you should upgrade your machine, the comparison makes a lot of sense. First, the 2.66 GHz Quad has the best price/performance ratio. If you start with the 2.0 GHz, you get 666 MHz more for $300, then you get another 333 MHz for a mere $800. So if you want to upgrade, the 2.66 is _the_ machine to buy. Second, there will be much less difference between a Quad G5 and a Quad Xeon. On performance critical Rosetta applications (like Photoshop) the Quad G5 will be stronger. In that case, it doesn't matter how much stronger - you won't upgrade, that is all that matters. But if you have a dual G5, then the question whether to upgrade or not is really interesting.
And we need to know whether apps use four cores or not. In many cases, changing from two threads to four threads is very easy (that is if all the threads to the same work; it is much harder if the threads do different work), but the app uses only two threads because most machines had only two CPUs. As an example, early versions of Handbrake didn't gain anything from Quad G5s; the CPUs were 50% idle all the time. People complained, and it was changed. The same thing will happen again, especially since _all_ Mac Pros have four cores.

Edit: Please ignore this post, I can't count!!!
If you buy a Xeon 5160 (3.0GHz) at the moment they are �570. Apple are charging �530 to upgrade from Xeon 5150 (2.66GHz) to the Xeon 5160. Bearing in mind that you can probably sell the original 2.66Gz chip for around �300, it would be cheaper to buy the lower spec Mac Pro and upgrade yourself.
It's not something I would do myself, but some enterprising dealer could easily do that. In US prices, difference between two 3.00 GHz and two 2.66 GHz chips is roughly $300, and you could sell the 2.66 GHz ones at a premium because they had "extra burn-in testing" :-)
Seriously, the problem is getting money for the 2.66 chips.

To me the answer to the whole IR/Mac Pro/Front Row thing is obvious - put an integrated IR receiver into the keyboard. The keyboard would come with the Mac Pro (unlike the display) and is rarely under the desk. :)
Plus they could sell the keyboard for any Mac (including ones that don't have Front Row - they could include the app with it).
Wow. Why didn't I think of that?
Well, regardless, I still think a Cinema Display update is badly needed, and if not alongside new pro towers.... when?

I'd take an iPhone over an android any day, but let's get real--the apple community is having a field day with this because of how much the competition has stressed "open" over "closed" in the past. Really the whole argument is so bogged down in brand loyalty that it's not even worth having anymore.

If Universal get cash as 'compensation' for stolen music, then presumably once you have paid the 'compensation' money, you can steal as much music as you like. Cool.
Apple doesnt really sell music - it sells iPods and offers the music at cost (or close to it) to support the iPod. Its a smart move , and its a pity that almost ALL of the iTunes cash goes direct to the record companies.
I used to work in the music biz, and a bigger bunch of thieving clowns you have yet to meet.
Most artists get 6-8% of the CD sales. Yes folks thats a big fifty cents or so on an average CD sale.
But because they give you an advance against royalties, which you spend on recording and PR etc. etc, only the very successful (a huge 0.5% of bands) ever make any money. Its a losing gamble and it turns music into a commodity - which it shouldnt be.
This battle will run for a while yet, but there is hope that the DEMISE of record companies is on the horizon.
With computer recording etc., its not necessary to get a record deal - good music does exist outside of the music industry machine.
Maybe Micro$oft will implode too - the zune fiasco suggests that they are up their own arses as far as common sense goes.....

Impossible.
Apple's no longer supposed to care about their Pro software.
This will never happen.
A lot of pros have already left Mac, but I have been holding out. However, this is the last straw. If the new FCP disappoints I will be jumping ship, buying a high-end PC and switching to Avid or Premiere. I just can't stand the frustrations anymore of watching every consumer itoy get upgraded, and then the Pro stuff getting shafted.
The time is now. The new FCP had better have something equivalent to Mercury Playback, optimization for RED footage, different HD codecs, real-time playback, 64 bit, multi-core usage, etc. If it's a dumbed-down consumer product I will be absolutely livid.

I don't have one of the Intel Macs (yet) but I have had excellent service from Apple Care whenever I have called. My wife's 14" iBook had the logic board replaced, 4 working days, and I sent my daughter's iPod mini in and it was repaired in no time ( I ordered her mini the day the became available-some teething issues I guess.) I had an AirPort Express replaced with no questions asked recently. I have never had a problem with Apple Care support, I don't expect to have my calls answered one the first ring when I call, that would be silly. These days being on hold for 10 minutes is one of those things. I agree with the other posters who said that the complaints get all the press. I try to always comment to management when I receive excellent service because compliments are rare these days, but complaints are common. Like the affulent med student in earlier post, I too am a switcher and I do NOT regret it for one second. I would not go back to my IBM Thinkpad if you paid me to.

I think that a lot of people forget that the first iPhone did not have GPS. It helped you find where you were by locating Wi-Fi hotspots and triangulating cell towers. Sometimes it would get you pretty close to where you were but sometimes the results could be fairly maddening. We always referred to this as fake GPS back then.
Now with the combination of real GPS and these other two methods, it is a very accurate system. And fast. I believe Apples description and only hope that the software update does not reduce speed or accuracy of what I have now come to expect.

What so many fail to realize is iOS was made for the iPad from the get-go. It's been mentioned many times that what became the iPad was in development longer than the original iPhone.
This goes to show that iOS conceptualization is light years ahead of Android. It's so obvious Google is scrambling, and seems to be making this stuff as they go along, without any sense of a master design guiding the way.

So the interesting fact is:
Verizon iPhone release didn't help Apple to stop losing marketshare although everyone said the deal will quadruple iPhone sales. :rolleyes:
iPhone Q1/11: 19 million (+ 2.5 million)
Android Q1/11: 38 million (+8 million)
Ouch. No wonder they are now sueing HTC and Samsung. If you can't beat them in the market, beat them in court. Apple must have learned that from Nokia (like they learned the choppy animations when you start third party apps in iOS 4.3.2 from Symbian).
Sigh. The iPhone is still gaining market share. Not losing market share.
