"If you see a stylus, they blew it," Steve jobs famously said of pen-enabled computing and, like its predecessors, the iPhone 5 does not support pen input. Yes, you can get third-party capacitive styluses that will work on the iPhone 5, but these little sticks do nothing more than give you a thinner finger.
Want to scribble down some notes like you do on paper? On Android, you can. Samsung's Galaxy Note and LG's Intuition both offer large screens, active styluses and deep pen integration into the operating system.
On the upcoming Galaxy Note II, you can hand write notes on your calendar, on the backs of JPGs and in half a dozen other places throughout the OS. You can even get previews of emails, photos and videos by hovering the Galaxy Note II's stylus slightly above the screen.
