The returns are in. in the fast-growing state of wireless networking, Wi-Fi has won by a landslide. Wi-Fi has just about everything going for it: cheap chips, free spectrum, public hot spots sprouting up like espresso machines and magic that's migrating from geeky computers to familiar products like cameras and TVs. In ads, commercials and blogs, the Wi-Fi Nation Googles merrily from parks and patios, beaches and bars. I've been a member of the Wi-Fi universe ever since I set up my first wireless home network early in 2001. Two PC cards and a router cost me $619.80 then and died after a year or so; today they'd go for $150, work better and last longer. For the past two years my wife has been reading her e-mail from the comfort of the sofa, and I've researched stories from a chaise on the deck.
