I got a Palm Tungsten-e2 for $100.... what can I do with it? (OT)

I refuse to tread into OOT, so I posted this here.

My friend got two Palm Tungsten e2's for free from his work and I gave him $100 for one with a 512 MB SD card.

My question is... wtf can I do with this thing? To me it just seems like a glorified address book and calendar but I'm sure someone here can come up with some good uses.

Apparently, they are decently nice. $250 or so retail.
