I am a very happy Note 2 user (fastest phone ATM) and I was thinking of buying the new iPad 4 but I have some questions about iOS. I hope more-experienced iOS users will answer my questions: 1) if I save a picture from Safari or Mail app, is the quality reduced? Can you rename pics once they are saved in photos app? 2) can you share a video or other media via Bluetooth or Wifi direct? 3) can I save songs from my friend's computer to my ipad without deleting songs already there in my library? 4) can I save an excel file locally and send it to someone else? Can I save any file / media locally that I receive in mail. Thanks in advance.
