When UMPC is thicker than a regular laptop which has full size keyboard, larger and wider screen, higher resolution, faster processor, more memory, faster and larger hard drive, internal DVD RW, longer battery life, and more ports, I don't really see the point of UMPC. Yes, that's my first impression on R2H when I compared it to my Fujitsu P7120.
R2H has a touch screen and smaller footprint, and also it's cheaper. But that's about it. Don't get me wrong. I knew the limitation of UMPC and understand it serves different target such as highly mobile users. But, the thing is R2H is not necessary more mobile friendly than P7120. I am mostly disappointed at the thickness of the unit. I don't like the way Asus designed how the battery gets attached to the unit. When I first opened the box and before attached the battery, I was thinking this one was rather thick. But, after battery was attached, it becomes even thicker: 1.6" deep.
I think Asus tried to achieve too much and forgot what UMPC is meant to be. Integrated GPS, camera, fingerprint reader are all fine and nice to have than not. But if the major selling point of your device is mobility, spent more time and resource on trimming down than adding other features which are not critical.
Sorry if my first impression sounds all too negative, and I know my view might change as I give it more time. But, I wouldn't have been this negative if the cons I found were something like slow performance or short battery life.
