I'm on my 2nd iPad mini. The original's battery neglected to hold a charge. Although I'm grandfathered in to unlimited data (AT&T) I decided not to use that plan with the mini. Instead, I cancelled the plan I had for my laptop connect card - and use the mini's "Personal Hotspot" feature (with the 5G, no overages but starts a new billing cycle, option). Can't give up the full-sized iPad(s) for many reasons, but the size and convenience of the mini is my "dream" device.
