I would buy an Ubuntu tablet in a heartbeat. I've been on a Mac for years now and I keep pondering the switch to Ubuntu but I'm having a really hard time justifying the investment in actually switching because these Mac's keep on chugging along.

The MS Surface is really appealing to me on form factor, but I won't switch to anything that doesn't have a Unix/Linux base. I really like the new iPad from a form factor standpoint...but I won't buy an iPad specifically because I'm not going to be coding on iOS.

An Ubuntu tablet would entirely fill my need.
