We ought to stop worrying about OLPC. Great kid machine, and admirable purpose, and it will probably (we hope!) make good things happen around the world. But a machine for you? I doubt it.
Impossible to use, for me, anyway. Kid-sized keyboard. And I find Linux unusable in 128MB.
It would be an ok Plan 9 or Inferno machine, but, there seems to be little interest except among us Plan 9 and inferno guys. And you still can't type on it.
