Just a terminal? The N800 may be small... but size doesn't count.

You could have the N800 do all of the computing normally done by an entire time-sharing mainframe from that era... all while you watch Star Wars. (And you would have tons of storage left over to spare... so you could probably do all of the work of many mainframes if you did batches.)

EDIT: Sorry: we don't need no stinking batches.

EDIT2: Make that The Lord of the Rings. The geeks from that era would like both... but LOTR would probably be more awesome to them.
