I have an Aluminum Macbook (late 2008) for about 2 and a 1/2 years now, but the battery has completely died and the macbook is simply no longer portable. I'm not sure should I just go and buy a new battery or get a MBA (11 inch maybe? haven't really decided on the size yet) instead? I want to bring my laptop with me around to school for lectures and labs (mostly for labs), so portability is an important factor. I would probably use the machine mainly for surfing the net, taking notes (with MS Office), and iTunes (for my iPod) so i think having the MBA as my primary computer should be good enough? What I really need right now is something that will last me a while, at least until I graduate from university (in about 2 to 3 years?) and I'm not entirely sure if my MB can last me that long Is it a time for me to switch to a newer (better?) laptop? Or should I just stick with my old one?
