request for help - PDA cell phone combo

Archived from groups: alt.cellular.tech (More info?)

I am a medical resident who lives in Omaha, Nebraska (zip 68135) and
would commute for about 30 minutes across river to Council Bluffs,
Iowa (zip 51503) for my medical residency. I am looking for a PDA-cell
combo that has following characteristics.

1. Must have a physical QWERTY keyboard
2. I must be able to install and use my medical softwares such as
5-minute-clinical-consultant etc. Normally, Windows CE or Palm
operating systems allow such software installation. I mention this
because I heard the cell-based PDAs have a different operating system.
3. Must have some feature that prevents PDA from
accidently/unintentionally getting on. My current PDA is Handspring
Treo 90 which i stopped using since its on/off button is so sensitive
that it gets on with a slightest touch while in the pocket of my coat
and gets the battery drained pretty fast.
4. Reasonable lightweight so that I can carry it around.
5. I want to consider both palm and pocketpc.
6. Access to web and email is of secondary importance.
7. Less expensive, the better but I know I will have to splurge
