It's a beta release, so I would not load it as your only OS. I would probably not load it at all unless you really were doing it because you like playing around with technology or need to evaluate it at all. If you do, try installing it on a second partition if you only have one machine, or better yet get another cheap machine.

I have been running it since Thursday. To be honest it is kind of a let down - Windows 7 is still there behind everything, just a little more difficult to get to anything. But in the end you pretty much can make it behave the very same way. all you get is the "metro" user interface at start up, which again seems to me to be a bit of a let down. Doesn't look good, doesn't really add any functionality, and right now there are only a handful of apps in the store, none of which are particularly impressive. I can see how this might work on a tablet device, but for a computer, it just gets in the way.

I do notice a little improvement in waking up from sleep, but not really an improvement on start up and certainly not in shut down. I think Microsoft my have been better off offering a separate metro product instead of trying to overlay 7.
