A lesser-known awesome feature of AvantGo was that it also functioned online. In early 2000 I was using AvantGo on a Palm Vx, IrDA connected to my cell phone, getting Internet access via my carrier's WAP gateway (PPP over CSD? I forget the specifics), to post to my 'blog and browse the web while riding the train.

It always made me think of those AT&T You Will commercials. I never sent a fax from the beach... but I sent a few from trains.
