propstm, I haven't put enough time in either unit yet to write up a review. So this is still impression or observation level. My expectation for UMPC might be a bit different from others since what I wanted was a portable laptop with touch screen, slate design, and acceptable battery life. I have a Fujitsu P7120 laptop and NEC Litepad tabletPC. I like both, but Litepad has miserable battery time and P7120 doesn't have a touch screen.
Honestly the feature that most interested me in R2H were SD card slot and better looking design. (But now I think Q1 overall looks better. Hard to look good if you're fat. ;) ) I was happy to have GPS and Cam, but it didn't really affect my buying decision. I tried Cam in my room a few times, and the camera software was really slow. Maybe R2H is not powered enough to run the software, but it took long time to load the software and operate it, and being unable to see let alone click the capture button was adding salt to injury. I can't say much about the camera quality since my room was dark and I know this type of cameras are meant to be used in bright area.
The screen quality of R2H is very nice, and actually I like it better than Q1's. Bright, Crisp, and less spongy and less sensitive. I experience almost none vectoring problem with R2H screen. At the same time, Dialkey is not very practical in R2H for the lower sensitivity but I doubt many people use Dialkey anyway.
In terms of performance, both seem OK. R2H generates some heat and fan sounds, but not too annoying. Q1 seems to run more silently. R2H has more RAM out of the box, but also has more crapware installed. You will need to remove quite a bit of those to run it in decent speed. I'm going to upgrade Q1 to 1GB soon, and hopefully it will provide some performance boost. Q1 has AVS feature which never worked for me. This is my second Q1b, and both units hang while booting into AVS. Not a big deal for me since I have zero intention to use AVS, but wonder this is a common issue or I'm just very unlucky. The screen rotation is easier with Q1. Maybe I haven't looked hard enough, but it seems only way to rotate the screen in R2H is using a tray Intel graphics icon. The problem is once I rotate the screen, about nine of out ten times, the taskbar gets messed and I can't read the bottom portion of the screen. Rotating the screen again is not an easy task when taskbar and task icon are not readable. R2h has a floating tip. I don't know which program provides this feature, but it's very handy. Most of time, it works like active digitizer screen.
R2H has a fingerprint sensor, but I didn't bother to use it. I have one in my laptop, and found it decreases the performance and is more annoying than useful. But, I can see it could be useful for some business users.
As for battery charging, R2H seems to charge much slower than Q1b does. Maybe that's because my R2h has bigger capacity battery. I noticed that R2H has 12V output compared to Q1's 19V. 19V is more close to "regular" laptop output, and for me, it's a good news since I can use external battery I got for my other laptops with Q1.
I haven't tested my Q1b's battery time yet. But many have reported that it lasts more than 3 hours with regular battery (3 cell?). Last time I tested, my R2H lasted about 4 hours with BT/WiFi on and screen brighness in the center. Honestly, I'm not thrilled at 3 or 4 hours battery life in ultra mobile device, and think this is the area the next generation of UMPC must improve heavily on.
Since I'm going to use a BT keyboard with my UMPC, a stand is a must. Q1b has an integrated stand. It's a bit flimsy and will probably be broken easily if pressure is on, but I'm very happy that it is integrated to Q1. R2H has a stand which looks more sturdy, but needs to be carried separately. One more thing in my bag, and one more thing to be protected. Not good.
The R2H box is pretty heavy and it has lots of goodies. Included case is not bad at all. R2H actually looks smaller in that case. The look is deceiving. :) Compared to that, Q1b comes with pretty much nothing. Just main unit, battery, case, and cable.
Oh, I almost forgot. One big advantage of R2H is point stick and more buttons. Point stick is working like just those found in many laptops. It works fairly well and even offer tapping. R2H has left/right buttons as well as direction and enter buttons. Unless you need to enter text, most of thing can be done with those buttons. Pretty handy for web surfing.
The feature most I like to have in my Q1b is an integrated SD slot. With SD slot, Q1 would be a great companion to my digital camera. I can carry a memory card reader, but less is better in mobility. The lack of Lan port in Q1b bothers me a bit. Granted I rarely use LAN port now that wireless is everywhere, I can imagine some situations (like in hotel rooms) I have to have a LAN port. But then I can make a bluetooth connection between my EV-DO enabled phone, so it might not be a big deal.
Lastly, regarding your question which one is superior, I can only say it's just subjective. It's no secret I'm much happier with my Q1b, but I can think of many reasons why some people prefer R2H and being perfectly happy with it. I just appreciate the small dimension and weight of Q1b since it was my top priority in UMPC buying decision.
Hope this helps and enjoy your Q1b.
