Adobe Mighty Cloud Stylus
Mighty is a pressure sensitive stylus that interacts with your iPad or iPhone via Bluetooth that also ties in with the Creative Cloud apps. Instead of working like so many other styluses on the market, Mighty also stores user data such as drawing elements so they can be pulled out and added to projects on other devices. For example, you could draw a car on your iPad, copy it to your Mighty, and then drop it into a drawing on your iPhone.
