As a IT person, have you though about the grift for your Mother? There are my suggestions:

1. Open a online banking accounts for her. - It can save her banking fee
2. A 3G Mobile - video calls , let her to see you, even we are working in office late and can't go home for dinner.
3. Introduction book of computers - Converting her into a IT person too
4. Install VOIP phone at home - let her make calls in a lower rate. If you are same as me, working oversea, this is extremely good idea.
5. Write a web calendar for your family. Then the mother know who won't dinner at home tonight.

But the best grift, is we are getting out of our computers and dinner with her on this Sunday.
