Hopefully the Help resources for the beta will be more informative. My limited experience with the W8 Developer's release was unpleasant and unproductive. I couldn't figure out how to some of what the Start button did; other things seemed less convenient. The Metro GUI on a desktop, laptop, or other non-touch system was a 'No Go', and I shouldn't have to jump through registry hoops to disable it.

I'll limit my comment in this post to the Start button, and not rehash my other previously expressed negative initial impressions. They've had several months to decay in my memory, and they'll be out of date in a few days anyway.
