If money is not an issue I would look into getting an IPAQ. This is probably more than you'll ever need, but it is the most expandable windows pocket pc in the market today. The latest models out today are the 3870 and 3850. Compaq is also coming out with the 3830 in a couple of months that has less RAM, for a hundred bucks less.

It might be worthwhile for you to know what is the best stuff out there, before cutting out what you really don't need. It has Bluetooth capability, the ability to do video conferencing, check email, surf the internet, voice intereactive mapping software (Travroute), and much more...besides already doing all the stuff you said you wanted.
