Gadget of the week - USB heating gloves (£14)

Brrrrrr. Chilly mornings and icy evenings play havoc with the frozen fingers of the average computer user. But help is at hand, as it were, with these mittens-meet-fingerless-gloves which plug in to your USB slot. After five minutes, the internal heating pads warm up by 10 degrees, giving a boost to wintry digits. Then, peel back the tips and your newly warmed mitts are free to type, text and game to your heart’s content. Still shivering? Check out the heated mouse pad and knee warmers also available from this website, devoted to all your USB needs.
