Besides for the novelty factor, I can't really see specialized personal AI devices taking off. Nearly everyone already has a phone which can handle the processing (some on device stuff should be coming "soon") and network connection, there's really no reason to have a separate device. I could see some "companion" devices becoming popular (watches, smart glasses, etc) but not really standalone devices that more or less just connect to an API to do inference.
That being said, I did almost order a Rabbit R1 this morning when I read that it came with a free year of Perplexity Pro (which is $200/yr) and the device costs $200. However, it was for the first 100,000 preorders and it's not available anymore!
