I have a laptop with a wireless connection. When I want to use my printer, I just connect to it. When I want better sound, I attach external speakers. I second what ejk002 said about security. Make sure that you secure your network. I live in the city and it blows my mind that I can get onto my neighbors networks. There are several security protocols available, I only know about WPA and WEP. WPA is the better of the two. As far as how far you can walk away from your router, it depends a lot on which router you choose. I would check out the reviews on CNET or one of the other computer sites. Wireless is the way to go.
