I know everyone's seen a ton of these posts, but I can't make a decision based on them. What I really want to know is if I'll be happy with the Macbook. I know it's impossible for you to really know that, but I'm terrible at making my own decisions and need help. I plan to buy one on eBay from a reputable seller. I can get a slightly used MBP (2.4) for $1700 and a sealed MB (2.4) for $1389. The only graphics-intensive thing I use is Photoshop. I currently run it on a late 2006 Macbook (2.4/4/120), but I find myself wishing for a brighter screen and better color. $1700 is my budget. SO, I can either get a brand new 2.4ghz MB and the three-year Applecare extension OR an open Macbook (period.) Would it be smarter to get the MB and Applecare? Or is the MBP really going to show me enough of a difference to make it worth an extra $300 and no Applecare?
