I'm in a similar position with a computer illiterate mom going on retirement.
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!" ;)
Incitement is everything. 10 year ago my mother was very reluctant to do anything other than type and print on the computer. Then, when I was going on high school exchange one and a half continent over, and said I wasn't going to plan my life around being close to a phone for the few hours a day when timezones lined up, but I'd be sure to check my mail, she learned in a weekend and haven't let go for a second since.
