What I want is a cheap, slim watch that will support data storage and payments.
Strapping data to my arm is an effective part of a backup strategy that I have already solved by 3D printing an addition to the strap to hold a micro-SD card. The data is as safe as I am.
The payments part is a little harder.
Connecting to my phone is just a gee-whiz marketing gimmick with little real, practical value to me.
