Gmail Scribbles goes to web and earlier
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.
Google hasn't said how soon it plans to introduce Scribbles to the native Android Gmail app, or if Windows Phone will get it as well.
