I'm still using my early 2008 white Macbbook, which has served me well for the close to 6 years that I've had it. I had to replace the hard drive at one point but it's been a killer machine all together. I'm starting to look for a new (to me) MBP, and began my search with places like themacstore etc. before moving to eBay/ Craigslist. I found a pretty decent deal on a early 2011 MBP that has some cosmetic wear, scratches and such, but nothing that looks too bad. The seller said that he has a receipt from where he took it to the Apple store in June of this year to have the hard drive replaced due to it being dropped. Should I be right in assuming that since the hard drive was the only thing replaced when he brought it in for service that there was no other serious internal damage? I feel good about getting an older machine, saving hundreds, and still getting several years of good use out of it but I don't know if I should be more concerned about the drop. What do you folks think? I'll hopefully have time lated this week to check it out in person.
