They finally made it.
they finally made it - it's called the "LiveDrive". It's essentially a wifi enabled pda with a 4gig harddrive.
Of course, what I'd prefer is something larger, less screen, 80 gig harddrive, and the battery life required to make it work for extended periods, but you've gotta go with what the market will accept I guess ;).
I can live over ssh, but there are times when I want to transfer large files, and it's often a procedure reduced to burning to dvd or cd those files that are just a little too large. The LiveDrive is the drag+drop to pda-type-device alternative.
