I had a 496 installed in my plane. I like it, but the screen was just too small and if you wanted to interact with airspace and other things you needed to hook on the screen, using the cursor around was a bit of a pain. I sold it and got a 796. The 796 is outstanding. I have used it for the last couple years flying around the country and locally. I have XM radio and ended up buying the GDL-39 3D. It is awesome for free weather, traffic (ADSB only when other ADSB equipped aircraft are around me as I don't have ADSB out yet).
The touch aspect of the 796 makes it simple to use. You can literally just touch the airspace you are wondering about or zoom in and out with ease through touch. It is a really nice piece of gear. It is also really good in bright sunlight and much easier to read that my iPad Mini.
