Today's PC's can do some amazing things. You can record and download music, make telephone calls, make movies, do you banking and even view people and things in other parts of the world, to mention but a few. The world of USB gadgetry also offers some weird and wonderful accessories.
First of all you will need some extra USB ports to plug your accessories into. This Homer Simpson multi-hub comes in at around $50 dollars and by all reports, it's a very mediocre piece of equipment. Anyway, let's assume that you have bought your multi-hub.

Next, you need some accessories to plug into it.
How about a drinks cooler to keep your beer nice and cool as you surf the web. These cost around about $30. I wonder what's wrong with a fridge. There is also a version of this that heats your drink for you and it's all powered by 500w power from a laptop (or desktop PC). It could be quite a strain on your laptop battery.
You could buy yourself a noodle cooker and a heating pad to keep you warm at night. It can get kind of cold once the central heating goes off late at night and you might fancy a noodle snack.
A USB toothbrush and a George Foreman grill allow you to eat healthily and brush your teeth afterwards. (I wonder what you do with the rinse water... where do you spit it?)
If you get neck and back ache from sitting too long at your computer you could always plug in your USB massage ball and give yourself a treat. While you at at it, plug in your USB eye massager and take away the strain.
If you don't like the dark and you are uneasy sitting in front of your monitor late at night you can always set up a USB ghost radar unit which will alert you if there's anything to worry about.

This ghost busting device comes in at around $50. Does it work? Well, if you plug it in and you don't see any ghosts, maybe it does!
There are many more USB attachments for you PC, some are very useful, like phones, blue tooth handsets, lights, cameras, etc., but it's hard to see why anyone would want things like grills, hot drinks makers and electric toothbrushes that need a computer to get them to work.
