Gotta say after watching that it makes me want one... however that desire is squashed with the fact that I own a number of controllers already and the fact that $800 is a crap ton of money, in fact looking at the difference between the standard Apex system (even before nearly $100 price drop), I'm wondering where the extra $300 is going, is wifi & a salinity probe and a few ports to run Neptune exclusive items really a $300 investment? Is current sensing really that expensive of an add on? I think the Reefkeeper products have had that for a long while now. If I was buying new, there's really nothing that's compelling me to want the newer version over the "classic" Apex.
Also would have been nice for them to have a rundown of all the modules they used, that way you won't get even more sticker shock to find out that $800 you just forked over can't do much of what they're doing because you need to buy all the add-ons.
I did think the switch panel was a snazzy touch, however it seems a modest investment to make for something which has been pushing you to use a tablet/phone as an interface that can do all those things as well. I would personally have been happy with simply having a big "FEED" button instead, everything else can be turned off/auto based on a swipe on a tablet/phone. The idea of mounting a tablet to the board was very cool too, I got a super crappy Android based tablet, that I have never really used because it can hold a charge for shit (get what you pay for, and it was free), but repurposing something like that would be neat, especially if you can have it give you a graphical display and all the other fancy stuff.
