Google's new Scribbles feature came to the Gmail app for iOS last week, and now it's available on the Playbook and devices running iOS 4 or Android 3.1 and up; you just have to use the web interface because it's not integrated into the Android app (yet?). The concept is pretty simple: hit the scribble button in compose view; doodle, jot, or sketch some verbal or pictoral message; and when you tap done, the image automatically attaches to your email. If you're adventurous enough to leave the comfort of a dedicated app and use an interface easily outperformed by MS Paint, go try it out — iOS users can download the Gmail app. Just don't expect too much from something called "Scribbles."
