It is now possible to get computers that will do just about every home application for a few hundred pounds, making them ideal presents if she doesn't have one already.

If she does, what about a peripheral or accessory to go with it? Printers, scanners, flat screen monitors, etc., are now very affordable add-ons/upgrades.

If she is a computer buff, why not get some software related to another of her interests? Most subjects have some sort of reference work available.

Of course, she might just be interested in the latest games! But consider also games relating to another of her hobbies.
