Initially tech curious, then probably older people who may not want to mess with phones? Perhaps younger people too? I could see kids using this to avoid the constant gluing to the screen. It's more of a toy than a serious productivity device at this point unless they release new stuff later (very likely).
Discussion
the elderly usually have problems with eyesight, and coordination that come with old age, and show especially when it comes to tiny devices + a lot of them are tech ignorant/avoiding, so i'm really interested to see how that part of the problem will be approached and solved, especially as i've been a 1-on-1 tech consultant/advisor/support for some part of my life
