I'm ready to upgrade my iPad2 16gb to a new iPad (probably mini retina) would like more storage space but trying to decide if the 128gb is really worth the very expensive price tag (I budget $30 a week for personal purchases)... I do hope this to be a long term purchase so I'm tempted to get the best option possible but since I do primarily use where I can access Wi-Fi and stream purchases thru the cloud I'm wondering if a 32gb or 64gb would be a smarter choice and not one I'd regret soon... any tips / advice would be helpful, thanks all
