Some say that our technological sense will overcome our common sense the day the digital Post-it is invented. I guess it is because the Post-it is designed to be thrown away, while technology should be built to last.
It appears that some designers at Sequoia Studios have come up with an idea that they would prefer not be called a Digital Post-it, but it is, for all intents and purposes, the most practical combination of Post-it and digital tech.
The E-notes use electric paper technology that has been under development for a long time now. These tiny pieces of e-paper are powered by a small solar captor that requires only one minute of light per day to work.
You can read more about the concept here, but here is a summary. The E-notes come in a pack of twenty-five, and a user can calibrate the date and time on all of them by writing on the first one with the stylus. As for each individual note, you can write or draw anything you want digitally, and then clear the message when you are done. So you can reuse the E-note when done, and even change its color!
So the E-note is a more practical way of leaving notes, and can be used and used again, until the stickum runs out. Well, these E-notes are still a concept just now, but I see a lot of potential.
