I just bought a new Core 2 Duo iMac and it has Wireless 'n' already enabled. I've already got a wireless network running smoothly but not 'n'. I'm streaming music/video to both my TV and Xbox 360 so speed of this network does matter to me. Is the speed increase of the 'n' over 'g' significant? The router I'm looking at is $100 for wireless 'n' so I don't want to spend that if theres not a significant speed boost. I'm not speaking technically either....I'd like to know from the experiences some of you have with this change to 'n'. Thanks!
