So I have be waiting for either the MBP or MB to update before I decided to purchase one. Finally it has! I need some advice on which one to purchase. I am going to be using it along with my iMac for music, pictures, email, skype, internet surfing, as well as working in Microsoft Office on Excel and Word for some contact work I will be doing. I have worked out the numbers and I can get a MB (with 4GB) for roughly the same as a MBP 13" (not modified). Which one would be better?
