You’ve gotta love the Post-Its. They are the best gadgets meant to remind you of stuff you need to do. Say for example I woke up one day and forgot to post the hottest phone news here on MobileWhack! A Post-It stuck to my laptop would remind me to do that.

But the yellow paper reminders although still popular will fade from our memory if devices like this E-Note prototype will ever get picked up and sent to mass production. The E-Note concept is simple enough. You have a piece of electronic paper powered by a solar captor. It can be stuck and unstuck easily and it has a visual alarm function which will let you know that you have to do stuff. To bad it’s too big for a wallet!
