PDAs

I'm looking for a good but competitively priced PDA over winter.  Preferably one with good battery life, USB hosting, the ability to charge through USB, and some form of SD (normal, mini, or micro I don't care) storage.  Something that runs nice, doesn't crash if I don't fuck with it too much, maybe one of them thumb keyboard thingies.  What are some good models to look at?

Palm's lifedrive is not bad.  A little expensive though; also has wifi inside.
