SketchBook Pro is an incredibly easy and straight foward piece of sketching sofware available for Mac or PC. (seriously it will take you only a few hours to learn). The folks at Autodesk have been working hard to make it even better with an update version available soon! Our friend Chris Cheung over at Autodesk has just posted an awesome preview of the up and coming release of Sketchbook Pro 2010. We couldn’t be more excited to get our hands on it and try out all of the new features! Check it out!
