There's a new Gmail Labs feature that'll allow Gmail users to see which of their Google Talk contacts are using Google Talk on their Android devices. In short, it's awesome. The typical green/orange/red lights have been replaced with the cute Android robot icon we've loved since day one. In Google's words:

Turn on Green Robot, a new experiment in Gmail Labs, and you'll see a robot icon next to people who are currently using Android phones. In the case below, Shirley is online with Android, Nicolle R. is using regular Gmail chat, and Chris I. is currently away but also on Android. Slatka is not an angry robot — she's online with Android but currently busy.

We think it's a great little idea that can help Google Talk users differentiate between who's on-the-go and who's on their desktop. And on top of that, the more that cute green Android Robot pops up the happier we are!

Activate 'Green Robot' in Gmail Labs today.
