One key use of the pen showcased by the company was for a new version of Photoshop CC designed for Windows 8 and Surface Pro 3. Adobe took the stage to demonstrate how users can combine the use of the pen and their fingers for multi-touch control when editing images.
Microsoft's pen also clicks on the top, much like a regular retractable pen that would be used for paper. Clicking it immediately opens up Microsoft OneNote on the Surface, so a user can begin writing down their thoughts instantly.
In another demonstration, Panay double-clicked the pen's button to take a screenshot, which was then immediately opened in OneNote. Panay then used the pen to crop the image, and began to draw on it. Once saved, the note then synced to Microsoft's cloud services.
Love these two features. Not for the general user, perhaps, for note taking and photoshop / graphics work it would be awesome to have this ability on an iPad. I love the fine pointed pen. I am not a fan of the fat rubber tipped iPad pens.
