Can anyone tell me the differences between Pages, iWork, Office for Mac, etc? I need a program on my mac that I can use to type documents, etc. I am planning on getting Pages but I'd like to know the differences between the rest of them. Also, I was wondering if Pages is part of iWork? In terms of purchasing, I am leaning more towards Pages since it is only 19.99. If anyone can help me it would be greatly appreciated. Thanks!
