Santa is bringing me an i Pad. I want a 64gb so I can load all my , CDs and clear some shelves in my house and use it to watch things on i-player, mumsnet etc. to get me out of my home office. I will use use it on the move but mostly at home. So lovely, geeky mumsnetters can you help me from your experiences: what is the difference between i Pad 3 and 4?
