I would go back to Russia.

Oops, maybe not enough money for that!

It depends very much on what you already have, of course. If I had time, space, and inclination, I would build myself a new computer. Or I would go to the DistroWatch site and click on the MadTux site to get a really cheap new Linux computer.

Or, here's an idea: buy one of those OLPC computers -- they look fun. Maybe you could find someone on the Mesh network they come with?
