The idea is immediately interesting to me because I often am in the car and want to remind myself to look something up and forget when off the road. I do not have a car with CarPlay. This would suffice beautifully.

...But that battery life absolutely kills it for me. I'd feel like each time I recorded something I was burning lifetime off my device. (Technically also true of rechargeable battery lifetimes, but it's abstract enough and minimal enough I don't think about it.)
