Yes, I'm on GPRS. Web speed is adequate but it's hard to gauge because I've become very accustomed to high speed connections (the slowest thing I deal with is 1MBit).

Seems no more painful than good ol' dialup.

Orange in the UK have clearly worked hard on their GPRS network. When I first dipped a toe in this water last year, it was awful; connections would silently drop, you couldn't get reconnected without powercycling the phone, the speed was dismal, etc. It Just Works now.
