I have a uMBP from late October 2008, got it the day the redesign came out. It's a 2.4 GHZ 15" uMBP with (upgraded) 4GB RAM and the 9600m gt and the 9400m chips. Usually, I replace my laptop every 3 or 4 years, but I was thinking that instead of waiting 4 years and dropping 2k on a new laptop then, I could sell mine now and put 2 or 3 hundred bucks towards the refreshed models. What do you think? How much is my laptop worth, any ideas? It's in great shape, but the bottom is a little scuffed up (no big or deep scratches though) Thanks!
