Gmail's new Canned Responses feature is very much like the Canned Responses in Helpdesk Pilot. Canned responses ideally help you get past the run-of-the-mill standard emails in no time. Either you can set a filter to automatically send an auto response or just pick a canned reply while replying to your email. This feature is usually seen in Help Desk Application like Helpdesk Pilot. Glad, that now even basic emailing applications have this feature. Great feature by Google.
