Back when,my first DB was a Leaf 17MP wifi which had no viewing screen at all, but rather, could synch to an HP PAD, long rendered obsolete by smart phones. The concept of field use remote viewing is still viable and I can't figure out why they discontinued it after 2 wifi models (17 and 22). With the availability of face-time on the iPad, it seems an easy enough adaptation, and still on my wish list as I don't care to be tethered in the field.
