Hey everyone I am currently using my 2006 Macbook, I got the model in December 2006 and it runs at the moment. However, my mac has an inflated battery and cracks here and there. But it still works and I used it mainly to surf the web and do Uni assignments and word processing, i am wondering is it time for an upgrade? I am in my second year of University and will another year and half after this year. Is it worth upgrading now, considering the machine i have currently?
