I was so annoyed that Google bought both Pebble and Fitbit, then did… absolutely nothing with them. Would’ve loved a low-end (sub $100) fitness tracker with ePaper.

Best thing they did was to release the pebble rights back to the creators.

I’m not saying it wasn’t safe, it’s just perhaps not quite as safe as some of the other ones.
