Last, guess why used airboxes are so cheap ;-) - their value is not much given the iDevices world
Well that is certainly true
I think the problem is we are all now so used to the fantastic touchscreen devices which companies like apple pour millions into developing. The offerings from aviation gps manufactures inevitably seem clunky and slow in comparison. I suspect in a few years external devices will disappear entirely and we will use smart phone apps to navigate both in the air and when driving.
In terms of aware versus other products on the market it offers everything I imagine most vfr ppl pilots would want- a simple to follow menu system for easy use in flight, clear and unambiguous warning of airspace using the CAA charts we are all familiar with. I struggle to justify the cost of e.g. Garmin 795 - at least for my purposes - when the aware box would do the same job for a fraction of the price.
