I have an HTC Flyer 7" tablet and find it great in the small RV4 cockpit. It is much better in sunlight than the iPad comparing it side by side with buddies holding their iPads in other planes. They always comment on the screen brightness comparison. It is an Android tablet and the program is Naviator. Not as powerful yet as Foreflight but definitely getting there. If you have an Android phone or tablet already download the app, you get the first 30 days fully featured free. The yearly subscription cost is $50 which includes all charts and plates, geo-referenced charts, updates, TFR's, airport info, etc. It will also route you via airways and allow rubberbanding. Geo-referenced approach plates, approaches, SIDS & STARS, and WX are coming. The tablet itself has built in GPS and I have never lost the signal. So far it has been very accurate. My personal opinion is that the 796 is an aviation dedicated unit that is extremely expensive to keep updated and when you get to your destination it gets to stay in your plane. With a tablet you take it with you to your hotel or tent (Oshkosh) and use it for video, pictures, mail and internet making it a great multi-use alternative that is very reasonably priced and maintained. I really like the Foreflight on the iPad but the 10" size is too big for 2 seat RV's that have a stick between your legs, sunlight readable issues,and it's Apple which I'm not a fan of but that's a whole 'nother discussion not for this site.
