Well it looks like it has finally arrived.
I'm still waiting for more detailed reviews on the quality of the keyboard before I decide whether to pull the trigger. But it certainly looks nice.
One positive is that, from the teardown, it looks like it's going to be really easy to mod the hardware. The keyboard has its own separate controller which appears from the connector to be regular USB. There's also a separate board on the right hand side of the case that appears to be nothing more than an on/off switch and a USB hub. If that's the case, then it should be trivial to replace the stock (slightly underpowered) Allwinner SOC with a Pi4, a small PC motherboard, or even an FPGA board.
