What’s New since Win 7 RC
Unlike Vista, which was furiously being developed right through SP1, there’s very little to report for Windows 7 when it comes to what has changed between the release candidate and the final version.
Internally, the issues we encountered with the RC and mentioned in our RC article have been resolved. Our stuttering HTPC no longer stutters, and Windows 7 now recognizes the JMB363 drive controller in one of our test systems correctly. At this point we have yet to encounter any issues that we can chalk up to a bug in Windows 7, which is a very promising sign.
There have been no notable changes to any of the programs or components of Windows 7 compared to the RC beyond simple bug fixes, so if you’ve use the RC then you’re going to find that the release version behaves the same way.
The only new bit of information we have is that last month Microsoft revealed that Windows 7 has greater CableCARD support, which we believe is a product of the new Protected BDA driver subsystem. Unfortunately the Digital Cable Advisor tool needed to enable this feature, and the associated firmware for the ATI Digital Cable TV Wonder (the only CableCARD tuner currently on the market) missed their release date of the 22nd, so there is no way to use this functionality at the moment. We don’t have any idea of when these will become available.
Externally, Microsoft’s hardware and software partners have been getting their houses in to order. Since the driver model s aren’t changing this time around there’s not nearly the kind of churn we saw with Vista. AMD and NVIDIA are the outliers here: they have been pushing out new drivers to support DirectCompute, Media Foundation Transcode, and the other features that are coming with 7 and/or DX11. Anti-virus vendors are the other group that stand to be most affected by the launch of 7, as they have been publishing new versions of their suites that include official support for Windows 7.
Finally, battery life, one of the sore spots with the RC, has finally gotten the kick in the pants we were expecting to see. We’ll get deeper in to this later when we look at benchmarks, but for the time being we’ll note that while the RC offered a battery life similar to Vista, the release version of Windows 7 offers battery life well ahead of Vista in all cases, and depending on the exact hardware used similar to if not better than battery life as compared to XP. It looks like Microsoft and driver authors have finally come through on significantly improving Vista’s lackluster mobile performance.

Well businesses that are stuck with an Exchange server and need computers on a Domain for it probably are still interested in a volume license.Heh, a small SOHO probably just get the "Family Pack"... or just keep running the WinXP machines they have into the ground. Why upgrade at all?

Yet another superficial look at Windows 7. Not a word about the registry and it's egregious affect on stability and performance. Not a word about the malware fest that is still Windows. Nothing about Windows very poor utilization of multi-core procs and large amounts of memory. No, its all as if the only thing that matters about an OS is the UI. Is Anand the only one at Anandtech that has taken an operating system class? Is he the only one who knows anything about OS X? It would appear so.Your brief "comparison" of Snow Leopard and Windows 7 was worse. Of course. It is not a minor upgrade at all unless..you only look at superficial things as you did the Windows 7 review. SL has had a few minor issues affecting a few people. Hardly "teething problems". The only differentiator between 7 and SL is now hardware? Unbelievable. When did Anandtech turn into CNET?
You can barely spell Linux apparently so I don't think we will see any kind of comparison there.
If you don't know anything about OS X or Linux then don't bother to mention ether in the future.

Did you make a Youtube video about this? lolxrror - Tuesday, October 27, 2009 - link
Which operating systems can I legally run on hardware I own:[X] Linux
[X] Windows XP
[X] Windows Server 2003
[X] Windows Vista
[X] Windows Server 2008
[X] Windows 7
[ ] Mac OS9
[ ] Mac OSX
When I visit AnandTech what computer trends/items do I find most relevant to me:
[X] Upcoming and exciting computer technologies
[ ] The latest and greatest media platform with DRM capitalization
[X] Upgrades for open and standards based x86 platforms
[ ] Hacks and modifications for closed x86 platforms
[X] Price/performance comparisons for gaming hardware
[ ] Articles denying relation of mal-ware output and OS marketshare

Hello clown boy!tomaccogoats - Monday, October 26, 2009 - link
While I can't support this tirade, I will say Anandtech definitely suffers in Mac and Linux areas. Then again, their slogan is "your source for hardware analysis and news", which I guess doesn't really warrant that it needs to be classed in those areas. Still, the latest Linux articles are August 2009, and then 2005!JimmyJimmington - Monday, October 26, 2009 - link

If thats all you got it isn't much. That is certainly a bug and a highly visible one. But it affects a tiny number of users who upgraded Leopard to Snow Leopard in a very specific way under a certain set of circumstances and even not all of them have the issue. Apple has a fix in 10.6.2 which will be out in a matter of days. To bring that up in the face of the yawning chasm of security vulnerabilities that is Windows 7 is pretty laughable.ibarskiy - Monday, October 26, 2009 - link
Once again, it's time you actually supported your statements with facts. What security chasm? Please cite vulnerabilities and extent to which OSX is not subject to them. And while you are at it, please explain how come it is that Mac OS got broken into faster when the compensation for the break in was the same between Mac OS and (at the time, but for all practical purposes immaterially) Vista [pwn2own 2009]. Oh, and MacOS was broken into twice to Vista's one time. So which again is more secure?ibarskiy - Monday, October 26, 2009 - link
Correction; it was Windows 7, indeed.
