Thanks all for this most enlightening discussion. I've taken the plunge and bought a BenQ U121, which has a gorgeous screen and pretty respectable keyboard. Some of the hardware (wireless, graphics) doesn't seem to be terribly well supported by the couple of distros I've tried so far, and my expertise being what it is I might need to offer suitable (liquid?) bribery in exchange for some assistance in getting drivers sorted out.
Unfortunately I'm in Timaru this weekend so may have to postpone serious fiddling until next week. Cheers, Roy.
