When BT first took an investment in Fon I thought it a great innovation. The ex-monopoly doing something innovative and useful that would leverage its assets (near-universal coverage) and provide a real consumer benefit.
Problem is, it doesn't work. I've tried using Fon when I'm away from proper wireless access a couple of times and it does one of three things:
(1) works until the connection just vanishes indefinitely
(2) works but requires you to log back in every few minutes or
(3) works but requires you to turn the connection on and off every few minutes
I lost and manually reaquired my Fon connection twelve times in the course of writing that last post. It isn't even a very long post and I wasn't doing much else at the same time.
