I tried it in a VM with 2GB RAM and it was hit and miss
* It's fast
* There are now
two control panels (the metro one and the one within the desktop environment, accessed via 'More settings' in the Metro one). If they don't remove the legacy one before release I can see this being a real dog of an OS. Imagine the confusion it would cause trying to explain something to someone else
* Icons are reused in different places with confusing effect. For example, 'Settings' has a cog and so does control panel. Clearly they're using cogs because they suggest configuration, but because the former is on the start menu you actually assume it's going to be taking you to control panel... and it isn't
* I'm not sure what the start menu is any more. Is start the tiles or is the menu in the lower left? Is the lower left supposed to global or the current application?
Overall I think it's interesting and definitely refreshing to see them trying to mix things up a bit. The problem is I can see there being some negative backlash to this DP and MS getting scared and turning metro etc. into a glorified overlay instead (a la Windows Media Center in Vista). The thing is, to improve they need to make even more radical changes. The legacy/desktop needs neutering in favour of the metro half of the OS - keeping both halves is going to make for a confusing mess (interested to see what they do with the two control panels issue)
