There's a long, narrow road ahead for Windows 8, and the Release Preview hasn't gone as far down the path as we were hoping. Here:http://reviews.cnet.com/windows-8-review/
Or this, As you can probably tell, I hate Windows 8 a lot. For the average, somewhat proficient user, Windows 8 hides all the things that makes Windows 7 so useful. Windows 8 seems to be designed specifically for tablets, for which it will be a great OS. However, for those of us who want to use computers to make documents, presentations, spreadsheets and graphic editing, Windows 8 will annoy us to no end.

So I'm thankful to those FReepers who have actually used it and describe it here. As you can see, you can post a review saying anything.
The raw performance head to head, comparing Windows 8 to Windows 7, that I posted from PC World, are indisputable, irrespective of what any individual reviewer thinks of Windows 8. Windows 8 IS considerably faster on the same hardware, than Windows 7.
As far as the metro interface for the windows 8 tablet is concerned, its based on the same metro interface that Windows phone 7 has, and that has received plenty of rave reviews. I think some Windows 8 reviewers are not thinking sufficiently out of the box when it comes to metro.
