I can see Chrome OS as a field solution where the hardware is cheap enough to be throw away. The fact that in a pinch, a techie could bump it up on Ubuntu to have the extra features at a cost of speed would make it a nice plus.

If planned with a minimum survival date (meaning if all guesses were wrong, it all fails, you are stuck with no way back) that does not exceed the time for a second trip, then it is not a complete do-or-die. It becomes a do-or-pray that the next trip does not have any delays. (Ok, that weakens the first motivator)

I'm not much of an au
