I am still using my MacBook5,1 as a main machine and it works better than ever. It will be 11 years old this October. I am not too proud to admit that it took me 10 years to open it up and clean the dust from the fan, not to mention replacing the thermal compound. Even with such poor maintenance it never missed the beat. I am wondering how many people out there are still using their 11 year old PC laptops with great pride(and can say that they work better than ever)?
