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. :/

OP here.  If anyone's interested, I did end up buying a netbook.  I bought this one http://www.bestbuy.com/site/olspage.jsp?skuId=9251445&type=product&id=1218068507849 for $270 with tax at best buy, which was the absolutely cheapest, smallest, bottom-of-the-barrel one I could find.  The battery life is awful (3 hours if I'm lucky), the keyboard is too small to type normally, and by normal computer/laptop standards, it's performance is awful.  But it's good enough to run Maple, Mathematica, and Sage simultaneously with no problems.  The only hitch was that the processor they used is old, and Sage  wouldn't run on it unless I rebuilt it from source. It wasn't hard, but it took around 8-10 hours to run.

In the end, other than the thing with Sage the only negatives are the battery life and the size.  It's a lot smaller than a laptop, but it's still significantly bigger than a TI92.  It's pushing the boundaries of "handheld", but it's alright.

(I also love that I got a recovery CD for a computer with no CD drive.)
