I just received my OQO Model 02 via UPS, and I must say its quite impressive. It's extremely small (only a little larger than the Nokia N800/N810), and its a full blown PC.
The HDMI output is excellent. I look forward to using it on business trips.
If anyone's in the market for a compact UMPC, this is it. I was going to look into Asus's UMPC's, but their big clunky size drove me away.
