There are quite a few ARM/Windows CE netbooks designed in China. Ubuntu clones are available for most of them.
I don't know of anyone who uses these seriously and really, before I buy something where touch is as important as a laptop, I'd like to either try the keyboard in person or at least hear someone on the 'net describe it. (I mean, for that kind of money, I'll take some risk... but I'd like at least some evidence that they might not be complete crap.)
