For years I have forgone using a wireless router at home... I never thought I would need or even want one. Well, while staying at Stevenyc's home in New York for a week, I have to say I'm sold! He has a great wi-fi setup and when I connected my notebook I suddenly discovered how great it is to be able to lounge around any part of the apartment looking at JWD and any other web site I'd like.
Shortly after I got back from New York I ran out and bought a wireless router... and here I am in my living room with my notebook looking at JWD while watching Start Trek TNG in my under pants.
The security on these wireless routers has improved dramatically since the old WEP days... I'm running WPA2-Personal with AES encryption. Hell, that is nearly impossible for even the NSA to break!
