best app for word docs and power points for university classes.
I am thinking about getting an ipad 2 for my university classes. I am wanting to use it for pulling up my professors word docs and powerpoints on my ipad. I would like to write/highlight on these documents with a stylus pen and be able to type on the documents. I would like it to also organize the documents into different folders for the different subjects I am taking. Before I buy an Ipad, I would like to know if there is any app that will do this. PLEASE let me know if there is one. If you are using it, how do you like it? . Thanks
