Yes, I'll probably do something like that for a while. It's less 
convenient because I'll have to be transferring files back and forth 
manually. But if used with a removeable drive, it would probably be more 
secure than having it plugged into my main computer by ethernet or 
serial cable. Especially if I compose and read encrypted messages on it 
as well.
