Hi All- I am a newbie on the iPad even though I have had an iPhone now for over a year. There are a couple questions I have straight away. 1) how do I add more storage to my device? 2) is there an app out there that I can use a stylus pen with to take notes? 3) I am leaning towards quick office to use for documents, would love to hear about yays or nays on this product. 4) anyway to hook up a wireless mouse to the iPad 2? Thanks everyone!
