In our early testing, Windows 8 Client crashed and burned more than the Server edition. Microsoft took the step of releasing a developer, pre-beta version of Windows 8 Client and Server to prevent losing developer and "mindshare". Every single item we saw was interesting, but until beta versions arrive, it's all a trial balloon. Interesting balloon, soars high, has cool innovations, but it's really a dream until we go past the developer version, past beta 1, past beta 2, past the release candidate 1, past release candidate 2, past the gold version, past production, to version 1.1 - which is the one you'll be interested in, if you can wait that long. Don't worry, we'll be testing them for you along the way.
