Sprint Phone/Pda

Our plan is almost up with verizon and Sprint offers much more family plan perks for less $$. I am looking at phones/pda's and I am stuck. I always thought I would get a palm pre because I love the palm format and now I'm not sure.

Given the choice of touch or no touch screen, blackberry curve or blackberry tour or palm pre or palm pixie which would be a better choice. I would like to use it with nursing central, phone calls, check email, not too much into games, music but do put my study notes on mp3 files. I also use a jawbone.

Any suggestions, ideas?/ thanks
