The Yoga Book from Lenovo is a new 2-in-1 tablet that runs Windows or Android. It comes with the 'Real Pen' stylus with real ink so you can write on actual paper, and your notes will be digitized into the Yoga Book. You can also use the Lenovo NoteSaver application and use the Yoga Book surface to write on.
Lenovo's Yoga Book features an on-demand Halo Keyboard with Haptic Feedback. This means the keyboard shows up only when you need it. The haptic feedback gives it more of a real keyboard feel, and it uses auto-complete and auto-correct for improved accuracy.
When the keyboard is off, the surface becomes a 'Create Pad' that you can use the Real Pen with. The Real Pen can detect 2048 levels of pressure, which can capture the subtle nuances when drawing. You can even use two hands: one to select on-screen tools, pan, and pinch-to-zoom, and the other to draw with. Since the Create Pad is separate from the screen, your hand isn't blocking the display as you draw.
The Lenovo Yoga Book is only 4.55 mm thin when open, and weighs just 1.5 pounds. It can get up to 12 hours of use on a single charge. It has an Intel Atom 2.4 Ghz processor inside with 4GB of RAM. It comes with 64 GB of internal storage, with the option to add a 128 GB microSD card.
