None of the current Palm handhelds has the two functions you list: integrated keyboard and camera. Those are completely in the domain of the Treo smartphones. You have choices of the Treo 7xx series and the Treo 680.

The Palm handhelds also accept universal (external) wireless keyboard if you wanted that functionality but it does defeat the portability somewhat. Out of the four current handheld models the Zire 72 has builtin bluetooth 1.1 wifi, Tungsten E2 has built in bluetooth with seperate capability for wifi and the most expensive TX has bluetooth and wifi built in.

The cheapest handheld the Z22 has no internet funcitonality at all. So if you were to get something refurbed the above 3 models would be good.

There other (non-Palm) brands of handhelds i've no experience with. Maybe someone else can chime in.

P.S Great find Jet!
