what I can say that it doesn't suck it seems use resources just as efficiently, if not more as XP. I installed it on my netbook and CarPC a week and a half ago. I have a Carnetix 2140, Lilliput TS LCD, RideRunner, Iguidance 4 running without a hickup. Just turn off the UAC and it rocks. I love the new keyboard, and if you install while your TS LCD is attached it will pretty much plug and play. But the calibration was inverted so I found TS kit here http://www.touchkit.com/drivers.htm and it rocks now. in short I LOVE IT. and this is coming from a guy who sick of windows and uses OSX leapord on a MBP as his primary machine.
