Jim Hughes, re your
/m14 - I'm not convinced.
It's far from cheap, true; but the numbers of people prepared to use it at this price are far from huge. Keep the price at today's level, and everybody will simply wait for a WiFi hotspot to be set up.
Cut the price to the level where people can actually use it, and I'm not sure the payback is justified. I'm looking at the (very poor!) 3G coverage that is already there. It's coming along with fits and starts and hiccups, but it is coming. Most phone companies are now starting to plan the slowdown of their investment in GSM masts, not a vast increase.
And the potential of GPRS isn't great. Once there's a choice between the 30K average speed of GPRS and the 300K of 3G or the 512K of WiFi/broadband, GPRS will not stay popular except in emergency, I feel.
