Hi, I had a huge problem with my Late '08 Unibody 15" MBP. I had it sent for repairs, and it was still defective (right when i picked it up and used it in front of them, the problems were still there... geniuses did nothing and told me they did...) So, Apple apologized and offered to replace the computer. I said OK. I went to pick it up and its been great. Only now have I realized that they replaced my 2.5ghz machine with a 2.93ghz!!!!!
