This site is absolutely amazing! When I purchased my new macbook, I really didn't want to spend the money to purchase Microsoft Office for Mac. My dad has a friend at work that told him about this program and it is absolutely amazing! It is totally free, you can use Microsoft word, excel, and powerpoint and it is totally compatible with other computers. I have to do a lot of file sharing for online classes (I am a college student) and it works perfectly. Don't waste the money on Microsoft Word, openoffice.org is the exact same program at the perfect price... free!
