BATTERY
One big mistake I made was comparing the OQO 02 with a double capacity battery with an Sony UX with a double capacity battery. After owning an OQO 02 and a Sony UX390n, I have decided that apples for apples the comparison should be made between real battery life. My sony UX390n with a standard capacity battery lasts just as long as the OQO 02 with a double! This means that using equivalent battery life that the OQO is heavier and the same overall size as the OQO 02.
NOISE
UX is a lot quieter.
HEAT
UX is a lot cooler.
KEYBOARD/MOUSE
After hours of use on the 02, my hands start hurting, yet I don't get this with the UX due to the ergonomic design of the mouse and palms, however I the 02 has a far superior keyboard. But what good is it if my hands feel like I have arthritis...and i've never had that feeling other than with the oqo.
Screen
I like the oqo better, you can do 1200x720 andthe extra .5 does make a difference. If the OQO was still stuck at 800x480 then I'd go with the sony, but the OQO wins with the screen. However, see my next comment.
DOCKING
Due to it using an Intel, the Sony wins with docking to external monitors (unless you need to do 1920x1200 or 1920x1080 and then you better make sure it'll do it on your monitor before buying the monitor). The external monitor support seems to not work well at all when the OQO has interpolated turned on, or at least is very buggy. The oqo has the dvd in the dock which is nice, yet you have to be plugged into the wall in order for it to work which means it's not mobile. I was disappointed when I learned this needed external power, but I guess that is why it is called a docking station and not just a low 8x dvd burner.
EVDO vs. EDGE
I have to say after having two 02 devices with Sprint. I would go with the UX390n EDGE any day...the disconnection issues with EVDO in New England states is awful. I hear it works well in the south and the west though, but if you live in the northeast then don't get EVDO unless you use a PC card with EVDO router which will use it's own special software to stay connected such as the Kyocera KR1 & Dlink DIR450.
BUILD QUALITY
I've had two RMAs with the OQO. A dead on arrival battery (yes I tried everything) and dead pixels in the OQO screen. The Sony doesn't have any RMA issues, but that isn't to say that there aren't any...but it does seem clear that OQO has more RMA issues than Sony from the posts in forums. I lost count how many RMAs I had with my 01/01+ devices, so the two RMA for the 02 is quite an improvement. I think it has a lot to do with outsourcing to Asia when Sony is right there in Asia with past experience.
PERFORMANCE
No comparison, the UX does what an Intel 1.33Ghz machine should do and combine that with the SSD speed...now don't get an SSD if you think it'll make your processor faster...it really just makes the hard drive read stuff super fast, but your 3D and such will be the same overall. The oqo tends to freeze up alot with most of my applications, which means a lot of reboots but if I do light stuff on it, it can handle it o rif I don't have too many things open and ask it to do too much, in other words, it will work if I am super patient and tread lightly. When using Intel based machines I don't have to tip toe.
WHICH IS BETTER?
So all in all, my view on the two devices is mixed. The advantage I see with the OQO is the screen and raised keyboard, yet all the other advantages that I thought it had over the UX have changed after owning both devices. Which would I recommend, well if I had a choice between the two...I'd pick the Sony just like meansquare. However, if my OQO had HSDPA in it and especially the HSDPA/GSM in it, then I might see saw over to the OQO because wireless internet is very important to me. But I suspect both Sony and OQO will be adding this in the near future. I think choice of processor is what has made the OQO not be what it could have been, and hopefully the next generation of the OQO will be Intel based. That is if Apple doesn't come out with an iPhone like UMPC device first. Although Apple doesn't seem to use their resources to develop new hardware devices one after another, they tend to take time to bring out an all new device from the ground up. So I suspect that wouldn't happen anytime this year.
CONCLUSION
In conclusion, I should have never compared the OQO double capacity with the Sony UX double capacity. If you can get by with very little battery life then the OQO standard would be your small UMPC device, but if you are considering the double capacity for the OQO then think standard with the UX.
P.S. .....
Ecsk2 asked me a good question..
Why did Sony, Flipstart and OQO come out with EVDO devices instead of HSDPA? Seems like HSDPA is more global, therefore bigger market.
