I just switched to Mac when the penryns came out; picked up the 2.4 with the 7,200 rpm HD. So far I LOVE the computer and am so happy I bought it. I decided to buy a 4 gig ram kit from Newegg.com since they had a $30 rebate, knocking the price down to $70 at the time. When I went to print out the rebate form today I noticed that the cut off date for the rebate was 2/24, but they advertised the rebate when I bought it on 2/26. I called them up, mentioned what happened and expected to have an argument. The woman said no problem and credited me for the $30. I couldn't believe how easy it was. They certainly did right by me and I would recommend them in a heartbeat to others. Just wanted to pass along my experience and mention once again how much I love my Mac!!!
