I installed ubuntu 10.4 on a 32GB Corsair Survivor USB. Runs great, install was easy. Boots fine into Ubuntu, but when you shut down and boot into Win 7 Ultimate 64 bit, Win 7 freezes up. It takes several reboots and use of the repair CD to fix what ever the problem is. So Ill pass on linux on a flash drive until the problem is solved, that, or Ill install and run it in Oracles virtual box.
