seeking counsel on linux PDAs with Wifi and GPRS

Hello list.

I am looking for a handheld where i can run Linux. I need to
access the Wifi and GPRS hardware.

Have you had any experience with this?

I don't have any experience with handhelds and i am quite
lost, there are a lot of models and it is hard to look for a
PDA that fits my necessities.

TIA
