I just called and talked to an Apple Rep from the Apple store in Novi, Michigan. She told me that there will be no way to upgrade my 1 year old Intel iMac with Core Duo to the wireless-N by hardware or software upgrade. I pre-ordered an Apple TV and was hoping to get a wireless-N router to get everything up to max speed but I guess that won't happen. I am at wireless-G right now. Does anyone know if this will be a big deal performance wise for streaming video from my imac to my Apple TV or should I just not worry about it. Thanks.
