Not to be a douche, but how often does a person find themselves out of range of an open access point? In my neighborhood alone there are 10. I had to start using WPA just to keep myself from stumbling onto other, lower signal power SSIDs when I'd fire up my laptop's wireless at home. With Starbucks and other chain operators apparently going over to an unlimited access plan, and typical coffeehouses, etc. offering free wireless, and cellular services (RIM, iPhone, etc.) that allow a perfectly reasonable simulacrum of wireless connectivity -- I guess my question is, why go to this much trouble?
