Microsoft's Office 2013 public preview went live today, but the company is also previewing a Metro style version of OneNote for Windows 8 testers. OneNote for Windows 8 includes touch-and-hold radial menus and one-tap search and sharing features with finger-friendly zoom options. Inking is also available for tablets that support pen input. Microsoft's demonstration of the OneNote Metro style app focused on the use of digital ink and a new radial menu which includes commands such as bold, italics, font size, and color options. The software maker didn't say when the app will be available in preview or final form, but we're expecting to see it hit the Windows Store soon.
