I am debating on upgrading as I have just been informed by Barclay Bank (Apple Credit Card) that any Apple purchase over $1000 qualifies for 1 year no interest financing. My MBP has had a clear spec snap on case from Day 1, so no scratches. It is 1 year and 2 months old and have 2 year Apple Care. This MBP has the 2.4 Core 2 Duo with a 250MB Hard drive and 4GB DDR3 memory. OS X Lion installed. Obviously, since there is nothing wrong with it, I don't need to sell it, but I'm wondering what its worth and if its even worth it to upgrade since a new MBP is about $1200.
