Supercalculators

I'm thinking about getting a new calculator.  I've had a TI92 for ages and ages, and I'd like to get something that's like that, but more powerful and faster.  From what I read on Amazon, the TI Voyage 200 is the best thing TI sells, but it doesn't seem like it's such a big step up from the TI92 to be worth $200.

Basically, I want Maple but on something handheld.  Is there anything else out there?  I guess I could just buy a netbook and run Maple on that.  That'd only be like $50 more. :/

Nintendo DS or iPhone in quality but with a much larger screen, it may be you'd run calculator software of some sort on such a device in the future instead of an actual dedicated calculator.

I was thinking about this but if the teachers in my mathematics department are any indicator math majors are too robotic to use anything cool or colorful or ergonomically designed.
They enjoy everything broken down fully into little block text and dots on a small dark screen too much.
