Google updated Gmail on the web to bring to mobile web users some of the features that it introduced in the Gmail iOS app just a few days ago. Those on a modern mobile web browser, such as Android 3.1, iOS 4, the BlackBerry PlayBook, or later versions of each can hand-draw Scribbles, or notes or sketches, to accompany their e-mail. It primarily relies on HTML5 to provide native features and supports colors as well as different brush types.
