iPAQ's and jornada's etc have a TS client but palms are different.
I checked their website, and it seems that most of their software requires and intermediary to communicate for enterprise purposes.
The main problem comes in the rendering as someone pointed out.
I was not able to find the megahertz rating for the tungstun-T's but if anything, they will be the only palms capable of using TS.
Obviously their programs might get you access to a command prompt or access to Exchange componets, but not the whole shabang like a
CE machine will.
Hopefully this new toy from palm has something for ya.
