I currently have the 12.9" IPP and seriously considering getting the 9.7 to work along side. The larger model is great around the house and even carrying to and from work as a laptop replacement but feel that sometimes the size makes it a little clumsy to carry as a truly mobile tablet. This is where I see the 9.7 coming in. It will be a little easier to use on public transport, move from quick meeting to meeting and generally make notes on the go. When i need the larger screen and not at home to use my iMac then the 12.9 comes into play again. Am I mad for have two similar iOS devices or does anyone else plan this type of set up?
