Here is mine way... 17" laptop and Samsung Blackjack cell phone with 3G, I tether the cell to the laptop using Windows Mobile Internet Connection sharing and I can play as near DSL speeds... If I wish. NOTE:NEVER USE FREE OPEN WiFi to play! you never know what kind of losers are sniffing the wifi traffic.

All Kidding aside I really do not play wow that often like this, just when I need to update the MOTD or post a run.
