I recently downloaded Bamboo Paper for my Windows 8 devices and have fallen in love with it. I've been using it exclusively on my Asus Windows RT tablet and have been blown away. I'm still working out all of the nuances and what it has to offer, but I'm quite impressed with the clean lines, variety of tools, and the way it handles color. I've been using my finger versus a stylus, but hopefully will have a new stylus in soon to really test the full functionality of the app. I've worked up some simple pieces as I play with it. While there isn't an option for layers or syncing, it's a fun app to use on the go. And it's easy enough to export the file to something like OneDrive and then import on another machine. Expect a full review soon.
