with some vaseline and a strong will you could make some good cash on the corn... oh wait a second.
Seriously, mine is indespensible. I have all my addy's, real and email, i get directions, weather reports, traffic reports, i shop online, PLAY GAMES while listening to a boring lecture, examine palma sutra, keep a record of my gas mileage, look up words in a dictionary, get sports scores, use it for white/yellow pages. You name it.
