There are (favourable) reviews of the different models at
http://www.umpcportal.com now. The M version looks like the one for me with its LED-lit screen.
I think Gigabyte should market this to students (such as myself) with perhaps a nice discount. It looks to be a device ideally suited to students (and others as well of course). I'd be happy to carry this around my University (Kingston). If Gigabyte were to give me a free one I think it would be paid for many times over with the advertising they'd get as result.
Well one has to try.
