Gmail Makes The Grand Gesture

Lloyd Dobler played a boom box outside Diane Court's window. Mr. Darcy saved the Bennets from embarrassment by getting Lydia properly married. And now Gmail is going great lengths to show it cares for us:  we can finally undo sent emails. 

There's a catch, of course: you only have 5 seconds after sending an email to undo it, though blog chatter claims a 10-second option is on the way. But 5 seconds is still plenty of time to act on the instant regret that comes from accidentally sending an incriminating email. Turn on this genius feature through Gmail Labs (look for the beaker icon in the upper right corner).

Though you had us at Gchat, dear Gmail, we've fallen in love all over again.
