A Bluetooth T9/multitap keyboard built around the actual keypad of a Nokia E52, talking to a phone or laptop. The engineering is lovely and unfussy–Alps switches, a proper battery circuit, ZMK underneath–and I admire the discipline of doing one small thing really well instead of disappearing down the mechanical-keyboard rabbit hole.
I understand the nostalgia, somewhat: multitap was muscle memory for precisely one generation, mine included, and I can still feel the rhythm even if I don’t miss it. The ingenuity, though, I’m wholly sold on.
