iPad3 or iPad mini for flying, any thoughts please?

[md 600 driver]

I have a ipad mini running on runway hd with the caa maps , pooleys, OS maps ,post code search and runways vector maps for Europe

I find it very good I can use it for a 4 hours of flight and still have 40% left on the power meter

I use the built in GPS ipad ( the one with 3 g capability and a SIM card socket which is unused )

I get notams and weather it even shows the wind direction on the map from the last Internet connection

I have it mounted on a ram mount 1 inch ballmount

The backup i have had from Runway HD is also very good
I did try a large ipad but found it too big the mini is just the right size

I don't work for runway or apple either
