I am purchasing a Macbook for college. No question about it. But I need advice on what different things to add to it, such as extra memory, applications, etc... What are your opinions on the 2gb memory vs. the 4gb memory? 250gb hard drive vs. 300gb hard drive? Microsoft office for mac? Applecare Protection plan? I am going to be a Political Science major, so I am going to be doing many research papers, essays, etc. I will also be doing the typical college stuff on it: internet, pictures, occasional powerpoints, rare spreadsheet, music, etc. These are the questions that haunt me. Feel free to add in any extra advice you have, because I am completely new to buying a mac because I have owned only PC's my entire life. I have played with Macs before, but never owned one, or bought one. Thank you!
