i bought my macbook brand new from the apple store in march 2009. i'm starting to worry because i know it won't be perfect forever. what can i do to preserve the life of my beloved macbook? i hardly even use it for anything other than web browsing and iphoto. any suggestions are appreciated. i remember on my family's PC we used to do a Disk Cleanup like every single day. i just want to know what i can do to make this thing last as long as possible.
