So I would like to use the iPad 2 as like an on the go computer, and I need to be able to use it for business. I would like to know if the iPad 2 can do these things: 1. Open, create, edit, and save Excel, PowerPoint, and Word files. 2. Open email attachments on the iPad 2 and save those attachments onto the iPad 2. 3. View PDF files. 4. Move Office files to and from iPad 2 with PC. 5. Create a folder that I can put all my Excel, Word, etc. files. Just like a computer so I can just open that folder and all my docs, spreadsheets, and etc will be in there. Can you please tell me if the iPad 2 can do these things, and how I can do it? Thanks in advance.
