I installed it on my netbook, I did require to install a separate intel graphics driver so that I could up my resolution so that the metro apps work, but now all is ok.
1280x960 is the recommended minimum resolution, but the metro apps will run at lower, just not netbook low :-)
I have found the new start menu great. Very quick to get new emails, as Gmail account is linked and Gcalendar and contacts are linked too so all running well.
I would think over the next month or two that we will see alot of new "Metro" compatible programs appearing so that integration with the Live tiles works better than the "what you actually see" view from the article.
I love the speed of startup, hibernate, and everything is nice and fluid, closing metro apps is cool, just drag from the top down. The wide interface is actually quicker to use than scrolling through the old start menu list and you can customise the tiles so that your favourites are listed first which I have found speeds up me using the PC, rather than what is suggested by this article. Big metro app integration over the next few months is going to transform the start menu into something that is really "teeming with life" much like the advantages of the widgets and homescreen design of Android.
Big thumbs up from me.
