Paul: sorry to take so long to comment!

My experience on the GNER WiFi link was pretty much what you might expect for someone playing with a prototype system - very disappointing.

But had the Wifi worked only for ten minutes here and ten minutes there, it would still have been better than GPRS was. I used GPRS all the way from Kings Cross to Glasgow, and I can asure you, it was only occasionally useful, and only for limited purposes.

If you want to send an instant message - and if you're in GSM coverage! - then it's wonderful.

But to actually shift data, it's too expensive, too slow, and too unreliable.

On my GNER journey, I urgently needed a small driver file for the Palm Tungsten. It was 14 megabytes long; at home, I'd have downloaded it inside four minutes, without thinking. On the train, I had about seven attempts to download it.

Each time I got to about two meg of the 14 meg file, we ran out of wireless range, and the download aborted. After starting the download around Grantham, I gave up around half an hour south of Edinburgh. A complete failure, nonetheless costing my phone bill for about 6 meg of data download!
