The Week in iOS Accessories: Pick and grin!
The $180 iNotebook lets you take notes with all the tactile comfort pen and paper provide—while letting you save the actual information to your iPad. How? By letting you actually write your notes using paper and a pen. A Bluetooth sensor in the notepad transfers your notes directly to an app on the tablet; if you’re AirPlay-ready, you can also take notes live on a screen, developing a presentation as you make it.
