This review is one of the most detailed that I have read about the Vega. And the author is right in many of the things he said.
The external design does not bother to me too much. Sony old U serie had a worse design for me.
There are few thing that bother me about this device:
1- No WiFi no BT
2- XP instead of Tablet PC Edition
3- Small screen size.
I do consider an external keyboard in these devices (Vega) as useless as the on screen keyboard. In my comment at Pocketables I asked the author to check how many WPM he can do in a UX180P and compare that to how many WPM he can make in a regular size keyboard. Dividing the number he gets in his UX180P by the number he gets in a regular keyboard and that's what I call Speed Coefficient. I'm sure that the speed coefficient in an UX180P is not bigger than 0.40
