Showing her high resolution pictures and videos of my first newborn little girl via email got her attention and a load of incitament to learn at least how to email/surf.
Her internet provider also sends her an SMS automatically when she get's an email, and then she rush to the computer to fire it up and read the mail to check out the pictures.
On a downside I now recieve nagging emails like "It was long ago I got pictures of my grandchild!" ;)
