purchased an ipad mini for the singular purpose of running foreflight on it - an electronic flight bag application which replaces a whole bunch of frequently updated aviation charts and printed material, gives convenient access to aviation weather data, simplifies managing a digital logbook, plus lots of hand-calculations like weight and balance that are not difficult but are more annoying to do by hand. in flight the ipad sits in a claw mount sunction cupped to the canopy where it's easy to keep an eye on adsb traffic, pull up airport information, and so on. there are other EFB apps that will run on android tablets but foreflight is more or less the standard and default used by most people so far as I'm aware.

since owning it i've found it's also very handy in the kitchen for viewing recipes as it can be set in place and read without being picked up in the hand as a phone might require.
