I'm being asked about utility of a Blackberry or similar, what are they called? "Portable personal communicator"? The need is access to email while on the road. The user is quite nontechnical. It Just Needs To Work. Aim is to have both personal and work accounts end up sent to the unit. I suspect the next request will be that responses be generated appropriate to the inbound address.
A strong appeal of the Blackberry is the keyboard -- the Palm's Graffiti really doesn't cut it here.
