I currently use the iFly 700 ( haven't upgraded to the new 720 - yet ). It works very well. I back that up for charts, weather, A/FD, etc ( and moving map GPS also ) with a Samsung Tab 10.1. My tab is on the Verizon network so I can check weather, etc anytime I stop even if the FBO is closed. Both are very easy to use/update and much cheaper purchase and keep updated. I do find that the 10.1 is a bit large for my cockpit though ( C-150 ). I am considering downsizing the 10" to the 7" version.
