I’ve been writing about very portable e-mail for a couple of years. I began with a telephone-based, pocket-sized portable electronic organizer with a built-in acoustic coupler, and last year I investigated the Motorola PageWriter 2000X with service through Skytel, all connected to a very limited wireless Westlaw project, and a RIM (Research in Motion) 950 through GoAmerica, that have very basic Lexis service.

This week I examine wireless service on bigger handheld personal digital assistants — the wireless Palm VIIx and the RIM 957. Both units use BellSouth’s Mobitex wireless communications network, but they don’t work quite the same way.
