ComputerWorld posted an in-depth review of Windows 8 Developer Preview

After spending several days with the Developer Preview of Windows 8 on a PC, it's clear that Microsoft's new operating system -- which offers two separate interfaces, Metro and Desktop -- is a transitional one between traditional computers and mobile devices. All of Microsoft's energy and creativity has been devoted to the new Metro interface; there's very little new of note for the old-fashioned Desktop.

As I tested Windows 8, I found myself wanting to use it on a tablet instead of my PC, because the big-tiled Metro was so much more visually appealing than the traditional Desktop, with a more intriguing feature set. After using Windows 8 for some time, it's clear that Metro is the future of Windows, and the Desktop the past.
