Title is a joke of course. The Surface Pro 3 comes with a pen. The pen has 3 buttons. They are not configurable. The top button opens onenote, that's it. The other two buttons offer right-click, and something else that is largely useless. Users complained about the inability to customize. A couple of months later, Microsoft now has the improvements shown in the article. I'll explain the improvements in easy to understand terms:
--The top button (which artists like to use as an eraser) is NOW...wait for it...no change! It still can only open onenote, that's it. The new "app" just offers a new place to set the option of whether you want it to open onenote the app, or onenote the desktop version. Who really cares? Not me. That option was already there in the control panel...but now the app has the option. WHoop dee do.
--The other two buttons? Still not configurable.
--Pen pressure sensitivity. A new feature? Yes! We can now adjust the pen pressure settings to your liking. Useful for photoshop users. Manga Studio/Clip Studio already has this built in. This is basically the only new feature.
Perhaps in a year, MS can muster up enough resources to customize the buttons.
