Q seemed like a very rushed to market device. He saw where the wind was blowing with stateless QR support across Jade & Seedsigner and animated QR PSBT signing flow.

All the videos I've seen of the interface look janky as hell, lagging refresh rate on the screen and menus buried in menus. They got away with it on CC, but a device with the form factor of Q should be delivering more and with more care to UX.
