680 is the new 644
I only went with the Pro upgrade as it was cheep enough and I got a screaming deal on the non pro. And I work on enough of my friends junk that having the other brands was nice
I have not found anything that "doesnt work" I know the AC works as I needed to cycle the electric fan and that worked(well fan didnt but)
For $229 you cant go wrong with lifetime updates. 99% in here dont need the Pro though.

I think I may have answered my own question. The 680 looks like upgrade from 644 (discontinued) and looks pretty awesome. Double the price of nt510/520 but looks pretty nice at first glance.
The BT model I bought does everything the nt510 can do and more but it's $40/yr (first year included). The kludgy software will likely make it a one year experiment for me. The foxwell is very very very kludgy interface reminds me of Atari 2600 or DOS 3.0. I would love to have a tablet interface with 1990 or better visuals and human interface. So that seems to be impossible under $1000.
