Hi all, I've had my Santa Rosa Mid-'07 MacBook Pro since it came out, but recently I had the screen die on me (still not sure why this happened). I've found a "low" quote for the repair, and it's $700 (CND). My question is: should I repair it, or go for the newest 15" i5/i7? The old one is a great computer, and I love it, but I was planning on upgrading either next year or 2012 if I could hold out that long. Is it worth fixing a three-year old computer that I was going to replace the following year? Thanks for any and all advice.
