I know that whenever the new iPad mini drops that supplies will be tight. Do you think that the 128GB version will be in greater supply? Since I'm selling my 64GB iPad 4 for $400 I was looking to get the mini 2 in 64gb capacity but don't mind spending the extra $100 to get the larger capacity if it's more readily available. I really feel theat the retina mini is perfect for me as it's portable and powerful.
