I love my iPad mini running Foreflight here in the US so much I'm even going to install 2 flush panel mounts when I do the panel. They're bloody brilliant. If I were legal to do so, I'd chuck the Garmin GPS right out the door and just have those, but alas, I can't since it's WAAS. The cool thing about having two iPads mounted is that you have:
Redundancy
You can run one IFR and one VFR to keep situational awareness.
You can put approach plates on one and keep the enroute chart on the other.
You can watch movies on long IR flights (hook the audio up to the audio panel)
You can run separate software, or a dedicated AHARS unit with artificial horizon or even synthetic vision.
Airgizmo has a nice panel mount unit for the iPad:
