Sadly, proly not till next year. I'm funding this myself and hardware is hard. Embedding it into a case has a whole lotta mechanical engineering challenges as well.
The desktop and tablet version will be released this year though.
I'd be interested in the phone version just for the keyboard. Closest I've seen is https://www.clicks.tech/ but I do not have an iPhone.
Yeah, I miss the real physical keyboards. I started with the Palm Treo smart phone in 2001 and stuck with Palm till they died. Better even than blackberry keyboards.
