Mine is 2009 15 inch model. I love it and I have been using it for more than a year. However, sometimes it is quite annoying to use, battery barely holds a charge, it sometimes completely freezes for around 10 seconds (with a lot of ata errors, I am assuming that the SATA cable is the culprit), fan are rattling and Nouveau sometimes breaks itself. The problem is that replacing all these parts would get really expensive, at least if I bought most of them from iFixit.
That is actually just disgusting.
