I am planning to buy a 15" Powerbook. I want to be able to use wireless internet around my house. Is there any real reason why I would need to buy Apple's Airport Extreme base station as opposed to a less expensive 802.11g base station? One in particular that I am looking at is made by Netgear and I can get it here for $64.99 which would save me $115. I don't know anything about wireless internet so any help would be much appreciated. Thanks.
