Often I find that my short term memory fails.<p>For example, when driving to the store I think of something I want to buy.
When I get to the store I can't remember it. Or I need to get something
from my basement and because I got interrupted on the way I forgot what
I wanted.<p>What we need is a simple "wristwatch" device that acts like a simple post-it
note with a button to record a couple words (e.g. buy bread), a button to play back the words, and a button to clear the words. The device should hold up to
20 messages.<p>Surely someone is capable of making this.<p>Note that a wristwatch form factor means I don't have to carry my phone
and play with an app.
