The iPad stylus. There have been dozens, but very few that stand apart from the herd. Fiftythree, the guys behind "Paper", that beautiful sketching app for the iPad, have created a stylus that they believe gets it all right. With a high quality build and a seemingly endless list of unique features, the Pencil may just be the perfect stylus for iPad-toting artists.
First, there's two versions. One is milled from a chunk of walnut, and the other is milled from a chunk of brushed aluminum. They're both gorgeous, and each has a unique feel in the hand. Second, it's shaped like a carpenter pencil--thick and rectangular. That means it's not going to roll away if you drop it on the train.
It has a rechargeable battery that lasts a month with normal use, and an eraser end that automatically engages when you turn the Pencil over. It also has a pressure sensitive rubber tip, palm rejection and blending controls.
Best of all, as of today there is now a Fiftythree SDK that app developers can use to integrate all of Pencil's wonderful features in their very own apps. Currently it's supported in Paper, Procreate, and Noteshelf, with many more coming soon.
These guys do things right, and it will just keep getting better with future updates and third-party implementations.
