The hardware of high-end PC can be shifted to 64bit environment at any time.
Windows is still 32bit though UNIX and Mac OS X have shifted to 64bit.

If, it is necessary to replace OS to do present 32bit Windows to 64bit. However, because the correspondence of the driver and the application is late, 64bit Windows cannot be shifted.

Windows Vista operates without trouble if there is a memory of 2GB. It is unquestionable for usual application software if there is an amount of the memory from 3 to about 4GB.
However, the application software in the future will become insufficient in 4GB.
It is near.

The opinion said enough with Windows XP is abundant. It is true when thinking about average user’s usage.
However, the change time of OS etc. was always said as for the opinion said enough by **.
If it is believed, 8MHz machine of MS-DOS might have kept still being used.

The development of the entire industry will not be able to hope the manufacturer like Microsoft that can say the leader of the industry shifts positively to 64bit of PC to pull performance improvement if it doesn’t take a measure.

If this movement is missed, it might be also near that the hegemony is grasped by the other companies such as Apple.

MacBook Air (January 2008 edition) is a version of Intel’s Core 2 Duo shrink that adopted the use of 45-nm process using Penryn and many people have the wrong idea. In fact, 65 nm using a version of the Merom.

Apple, which uses technology, and more, if you do not publish, but some information from the public, it can determine.

The 1: Apple’s own version of 45 nm and is using it as I did not say a word

Mac Pro is the core of eight to 45 nm version using the Mac Pro site, and so it is written, the MacBook Air referral process is not written in the rules. Apple’s own version of 45 nm and is also said not a word.

The 2: shrink version compared to the same die size of the object

Macworld 2008 chip size

LE80537 written and normal size compared to the Core Duo 2, but this is Core 2 Duo T7400. That is the version of 65 nm Merom T7400.
And the same die size.Rules in the process, if it is smaller die size, die size change.

Intel 45nm and 65nm chip

45 nm version of the left and right are 65 nm version of the Quad-core products.

The 3: SSE3

Immediately after the public announcement, the MacBook Air SSE4 Developer Note has been written response. It also adopted Penryn reason was mistaken, but later modified SSE3.
Penryn is incidentally from the corresponding SSE4.

So let’s use what it is

4MB L2 cache, a 800 MHz FSB specification has been published and can say at this point is the ultra-low-voltage version is not. Version or normal voltage and low-voltage version can be expected.

This article is expected to be low-voltage version.

This article is in some greater detail.

The CPU is used MacBook Air, Penryn used ahead of the technology package, Penryn (Santa Rosa Refresh) or Montevina version of the main board is almost the same stuff used, such as body weight is almost unchanged . Instead, the battery life or performance either, or both things will improve in the coming six months or so may be.

And decrease development time, Intel and Apple’s recent honeymoon after considering the competitors ahead of Intel’s latest processor is the first to appear and will be Apple’s MacBook series that have the potential to become.

I, which was announced at MacWorld 2008 Update iPod touch of a 2,480 yen fee was surprised because I did not know. However, the official added that if the Apps, the problem is not thought to buy.

JailBreak is my iPod touch with the various Update without using software. SDK will be released until the Update is not thought necessary, Maps, and the new features could not stand.

Update before iTunes to Authorize Computer, it was a message that came out on the Update will work for a moment and look back at the end.
End in a moment, on the left tab of iTunes Shopping Cart also be downloaded so it does not appear a total of three times about his purchase.

When it is not (because of the belief that) the same thing was repeated three times, but not the iPod touch and confirm, after already Update.
Looking at the screen’s iTunes Store, iTunes Store in the upper left corner of Quick Link Account, in the Purchase History purchased, but will be three times that were recorded.

I noticed immediately Report Problem button down it is a purchase from a total of about 16 hours after receipt minutes 7,500 yen received in the mail.

Update after the Mail JailBreak before setting data of the email was to take over the question, but the waste can be used for about 5,000 yen was cancelled? Anxiety.

Addenda: January 21, 9 pm

Thursday morning ordered the immediate pressing Report Problem is, Monday night’s reaction to not do anything. 24 Hours will be from the past, Web inquiries from the desire to send a cancellation.
The receipt itself is coming soon.

Addenda: January 22, 9 pm

Send inquiries after business hours from 6 to reply came as a total of four rather than three, so I was buying, and the three of us to cancel it.
The 2,500 yen to 10,000 yen to buy a fool I was. Dumb better.
