Recently I have been tired of Windows. I totally hate it and want to buy a Mac Book Pro. I just don't know which one. The 15" or the 13"? Normally, what I do on a computer is this: I use Facebook, YouTube, Twitter, I also download music from iTunes, edit videos (I love iMovie, so that is also one of the reasons I will be changing to a Mac), make presentations, and a lot of Word documents. Sometimes I upload pictures from my digital camera. I think that the screen of the 13" is just too small. The 15" seems a good fit for me, but I just haven't decided. I can afford both, but would save money on the 13" model. Also, I will be buying software to make documents, presentations and spreadsheets. I have both Keynote and Pages in my iPad, but I have never tried it on a computer. Apple is always more "cleaner" and "prettier", but Microsoft has more compatibility. Also, does anybody know if Apple will be updating iWork 09'? If so, I wouldn't buy it, I would buy it after the update. I am from Guatemala, and have been thinking about using Apple's educational pricing. Does anybody know if I can use the discount? If so, what do I need to show?
