Dedicated devices are often mediocre because they have to be cheap and have crappy HW and a small battery. Look at Rabbit R or Humane AI Pin. You already have a high quality expensive phone, no need to buy another crappy electronic-waste-since-manufactured device

... Unless they do bring more convenience. A popular example are smartwatches. People have a perfectly good clock, stopwatch, sleep surveillance device on their phone, and still pay 300-900 dollars for an AppleWatch.

Why? Because looking at your wrist is much more efficient and fast than getting your phone out of the pocket.

A phone-connected 'AI necklace' to act as a trigger and communication device to an AI interface ( maybe even a small camera ) might be more convenient than fishing your phone out of your pocket as well.
