OK, i wont go into too much detail, but here is a brief summary of what I think is the way to go:
Davis should really concentrate purely on the sensors - they are the best at it and it is something that is of extreme importance.
Then, they should make it modular, in other words, allow connecting your tablet etc. directly to it - they cannot compete with companies such as Lenovo, Samsung, Apple etc. so even if they developed a new tablet-like console, it would soon be outdated.
Next, this modular system would allow adding extra sensors. Instead of offering the console they could have sensors for snow depth, fog, lightening?, IP cam, emissions etc etc. And it would be ideally possible to connect all this into one single device and have this sent as one data package to some central unit.
And this central unit would be able to send the data directly by Wifi, or connect by Modbus, or simply by a cable to any external device - tablet, smartphone, sent directly to server etc etc. And this would then be an ideal system... imho....
