The iPad Mini is produced in wi-fi only and a wi-fi cellular models, the wi-fi cellular model has full built in GPS the same as the normal iPad wi-fi cellular model that I currently fly with, according to Apple all iPad apps that currently run on the large ipads will run without problems on the iPad Mini hence the 7.9 screen size. (maybe confimation from the SkyDemon Team on this?) They are available for pre order from today 08:00, the wi-Fi only version delivery dates are a couple of weeks and the wi-fi cellular version is out for delivery late November. I have ordered my cellular version of iPad Mini to replace my iPad3 the sole reason being size. Should be ideal for the Robin cockpit.
