Another day, another contender for the smallest in the world ever. Today the gadget in question is Sagem's H4 bluetooth headpiece, which they say is the smallest on the market - for this week, at least. Mind you, it certainly is a little 'un. Weighing in at just 8 grammes and measuring 35 x 18 x 12.5mm, it somehow manages to find space to store two of your favourite numbers, and will give you 5 hours talk time. It's currently available online only, and will cost you £53.
