I am an American living in Tanzania and although 3G is here (in certain major towns) buying any tablet with 3G from the US forces me to pick a telephone company so having a tablet with wifi + tethering my phone is a must. I'd be surprised if others wouldn't rather have an unlocked 3G option for international use.

I have two HP 2133 netbooks (120 gb HD version) and have Fedora 10 on one; Ubuntu 8.10 the other. Other than the VIA graphics (Chrome 9) not working out of the box, I've found Ubuntu to be the better of the two for installation and wifi support.
