To be clear, the "internal battery" for the 720 is sized to allow the unit to survive brief (~5ish seconds) power outages, as opposed to the 700 which can reset from a power glitch lasting only a few milliseconds.

Also, the 720's wi-fi does, in fact, allow it to connect to external devices (specifically, the Skyradar ADSB receiver).

Finally, the 720 does have a somewhat faster internal processor and more internal memory, which may eventually allow it to support more features/capabilities than the 700 (though as of today, that is not the case).

Geoff,

I upgraded from the 700 to the 720 and my experience is that the 720 is superior. Definately (to me) worth the difference in money for the brightness and also for the many extra features and speed. You may also find the "Vector" mode, which clears the screen of most of the chart background leaving only the essentials like airspace, flight path, etc., will make it even easier to read in bright sunlight. I seem to remember a hood is also availiable for the unit, but if not it would be easy to make one.
