I've had mine for 30 months. And man - it's still damn good. I've only ever had a PC (family windows desktop computer) and after a few years everything gets slower on them, you can't even open word without it freezing. But on my Mac? It STILL opens applications fast. It's still a good computer. I take good care of my Mac but it does show it's age in say the cover - I have a few scratches or dents on it since I had to carry the Mac with me a lot and take it to school. But overall, it still looks good and works well. I'm probably going to take it to Best Buy and do a cleaning sometime, they say you should every year but I've never really cleaned it or had the fans cleaned. But the computer doesn't really seem to need it - it's still fast, overheats sometimes but that seems to be a problem for other Mac Users too. I always clean the screen with a glass cloth and keep it looking good. Over all it's still a good comp. How are your Macbooks doing? Do you ever take them in for cleaning or do you not feel the need?
