Hi I'm looking at the prices for Microsoft Office and the prices are too high. I just need it for typing documents. Also, is it possible to just get the word program. I don't need excel and powerpoint. As you can see i'm sort of new to mac's, would it be compatible with the Windows version. Lastly, I guess I would have to buy an external drive to save my documents with the A:/ drive. Can someone please answer my questions? Thank You!
