I have used a Nokia 5190 with the Nokia Data Suite software to connect my lap top to a dial-up ISP for a couple of years. Works great but the rated speed is only 9.6K. Actual measured speed upstream is no more than 3K and downstream is a little less than that. A 1Mb file takes 45 minutes or more to download.
A local ISP just started an 802.11b public access LAN here but coverage area is still very limited. Not at all comparable to the cell phone dial-up ISP coverage area. I have measured the speed for the wireless LAN at up to 850K upstream and a little less downstream.
Ricochet had a wireless LAN in 21 major cities but they went bankrupt last month and shut it down. Too bad-I heard the coverage was pretty good in metropolitan areas and the speed was a minimum of 128K.
