Interesting product. Curious how it will work.

I wanted to see what the price was going to be but you have to enter your email address first. No thank you. I don't want to know that bad!

Exactly. It is some pre-crowdfunding project and they are probably trying to find out if it is worth doing. That by itself is a sign of no faith in your own product.
With so many crowdfunding project going wrong i think crowdfunding is not the best way to find out if a project is worthwhile doing. Just build it, show it to the world, fund it then build the fancy one with crowdfunding to get economy of scale.

i'm guessing it is something similar to this in concept:
https://learn.adafruit.com/7-portable-raspberry-pi-multitouch-tablet?view=all

but the problem with such designs is that the cost of RPi + LCD panel + LCD driver board + battery + enclosure is substantially greater than the cost of a cheap android tablet. on the plus side, you do get more I/O, and the opportunity of having a bigger battery.

an interesting idea might be a standard android tablet tethered to a RPi zero via USB OTG. with suitable software running on each, one then gets the extra I/O of the RPi. then again, an MX470 could probably work equally well as an I/O expander while consuming much less power than even a RPi zero.

cheers,
rob :-)

Since you mentioned USB OTG I thought I would share a quick observation with the serial function. It's purpose is to act like a USB to serial converter in software to give a terminal session. Using Jessie not Stretch, I had no problem getting it working but after a couple of days the serial function as well as wifi would stop working. Cycling the power would always get it going again for a couple more days. I hope it gets fixed in the latest OS release which is Stretch.
