Not that impressed by it installed on a netbook, with a crappy trackpad.
I imagine it would be way better on a laptop with multitouch, it's definitely a touch screen OS. Apart from that it does run smoothly considering it's got an Atom processor in it.
If anyone wants to try it out you can download the the fulll 64bit or 32bit enterprise version and run it for free for 3 months from
here.
I recommend using a separate hard drive or partition though and back up all your Windows 7 data just in case. I certainly won't be upgrading for my main PC, but I think I'll install it in a virtual box on my MacBook Air as a few people on YouTube seem to have done that successfully.
