The leadership behind this project is f(x)tec. While they're not outright scammers they have a TERRIBLE track record in delivering products like this. Just look up the old fxtec community forums or the indiegogo pages for the pro1 / pro1x.
It's just data points but so far the modus operandi was to take pre-order money and then take years to deliver a bad product with no aftermarket support. There were always new excuses about what happened (shipping company stole our stuff! chip reseller scammed us! etc) but no transparency. The reality seems to be they ran out of money and instead of being upfront about it kept making up new stories why nothing was happening. The few devices they have shipped are basically unusable unless you're going to mod the hard- and software yourself (no security updates, issues in antenna design, outdated hardware by the time it ships, keyboard quality issues, you name it).
If you're interested in the device I implore you to wait until you can buy it upfront (ideally in a physical store) and return it at your convenience.
I thought I needed a keyboard too, but when everything is designed for a slab screen and your "productivity" phone randomly shuts down or has no reception in a major area, you gotta think about what productivity really means.
