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 he doesn't have one already.

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

Of course, he might just be interested in the latest games! But consider also games relating to another of his hobbies. If he is motorcyclist, for example, why not get a racing simulator?
