PDA suggestions

i dont know if this is the exact right forum but i thought it looked like a good place to put it
im looking into buying a PDA mainly for entertainment purposes like music and games but also a little bit for school using ot keep track of all my classes and such, im wondering how fast of a processor would be good for one and like what brands are good, i also want to be able to access msn via my wireless network at home its a 802.11b
any thoughts ? ?
