I am so excited! I have a CD Mabook 1.83 Ghz and I was talking to Apple Care support rep's(product specialist) about my Airport issue. She acknowledged there are issues and interviewed me and asked if I could send the Macbook in for investigation for a favor of a brand new replacement C2D 2.0 Ghz Macbook with 2 GB RAM! ( I had 1 GB RAM) . I took the offer! Btw, other than wireless-n is there is a noticeable increase in speed from the 1.83 Ghz to 2.0 Ghz C2D?
