I don't know how I missed this feature. I had Edge running and wanted to mark up a web page. My Surface Pen was not handy. So I wrote with my finger instead. Worked very well. Give it a try. Works on any touch screen device with Windows 10. Microsoft will have to modify their TV spot from: "You can write with a pen? You can say that again. I really like my Surface Pro 3." They need to come up with words that rhyme with "finger". Like maybe, "zinger".
