Rumor has it that Tom Owad may have mentioned these words:

Personally, no -- my cell phone consists of pushing 7 buttons and I hope I
talk to someone. Digital's only been here 2 years, and that's just
re-encoded analog - i.e. no games, web, email, etc... just voice. (Not that
I give a rip about any of that other foolishness.)

However, over at www.bitchin100.com -- one of the main proponents there -
John Hogerhuis -- has his cellphone hooked up via the RS-232 port, and is
getting ready to write an SMS app for the M100.

He already wrote DLPilot, a Tandy Portable Disk Drive emulator which runs
on most serial-based PalmOS devices. It's $$$ software for a year, then
he'll release it to freeware. My take: Give him the $$$.

;-)

There's been a few discussions WRT cellphone use on the Model 100 list -

I don't have full-bore searching yet.
