I have recently bought a Toshiba AC100-10D (it was quite cheap because it's now old, but the hardware is still quite similar to that of the new tablets). I bought it with the expections of installing Ubuntu on it (I don't really need Android - I have an Android phone which is good for that purpose, but I'd like Latex, R etc. available on a netbook).

I found some tutorials on how to install Ubuntu, but I didn't really have any success until I found http://salaliitto.com/~gildean/ac100/wiki/phh/ . So thanks a lot to gildean! I would recommend that you follow that guide if you want to install Ubuntu to your Toshiba AC100. At least until Ubuntu 11.* supports the machine better, see e.g. https://launchpad.net/~ac100/+archive/ppa .
