Email-keyboard on users' mobile when filling in email field


when a user fills in the email field, on a mobile landing page contact form - have the mobile keyboard change to an email-keyboard, thats when you have the nice shortcuts like " .com"  and " @". Fun for all. Easy implementation (i donno - just guessing here, a buddy told me to add this little beauty:   ), and its expected, and makes the users life a tiny bit easier.
