Well, like the title says, I can spend no more than $2,500 usd, and absolute not a penny over so please avoid the replies like "if you add just ... $, you could get blah blah.. Here is what I'm looking into: 1. Refurbished 17" Hi-Res Glossy Merom 2.4Ghz 7,200rpm $2,350 2. New 15" Penryn 2.5Ghz 7,200rpm $2,350 (after the student discount) 3. New 15" Penryn 2.4Ghz 7,200rpm $1,890 (after the student discount) My main concern is if the previous gen 17" nonLED merom screens are good enough comparing to the new LED 15" or 17" penryn MBP ones? Ive been seeing lots of complaints about the new LED panel defects, wondering if the previous gen 17 inchers had less problems. Please share your opinions ups and downs of each generation. Your opinion is HIGHLY appreciated!
