"Oh sure, Windows 8 does boot faster and it has a few new features, but generally speaking Windows 8 with its “not Metro” interface is junk. I've been working with Windows 8 in one version or another for months now and there is simply nothing about it that would make me recommend it over Windows 7 or XP for that matter."
A little later on in the article you begin to find out what the author really thinks:
If you want something better than Windows, go with desktop Linux, a cloud-based Linux desktop like Google's Chrome OS, or a Mac. Heck, try an iPad. Just don't waste your time with Windows 8.
I can't wait for the release of Windows 8, I really am curious if it will be received as badly as reviews seem to be indicating. Remember Ubuntu and it's Unity bomb. One size does not fit all.
