ISP's for wireless service on a laptop

[alkie]

makes sense. The thing is that they are keeping their desktop pc active, they aren't trading a pc for a laptop, they want service on both. Also want to be able to travel around with the laptop and I guess that is where the montly fee comes in, but they were just wondering if their is a cheaper service than the 60 per month that their current ISP wants to charge. They have AT&T DSL right now and are paying about 25 bucks per month.

They can still have their desktop connected to the router, any good router has ethernet connections where they can plug their desk top into as well as the wireless option.
My desktop upstairs is connected with a cable, while I am at present lying on the couch using the wireless option on my laptop.
As for a roaming service, I aint too sure of that one mate, anytime I had cause to use my laptop before in was in a hotel a year or so ago and it wasn't by a wireless connection.
