IRC on your mobile
I got a new machine today... It was pretty fun how I did it. I stayed on the #mobitopia IRC channel via my telephone while I was wandering around the stores—I would type in the make/model/specs and the price and ask the guys online to see what they could find in terms of comparitive prices and to get their opinions.
