Nike has been integrating athletics and technology for a little while now (their Nike+iPod app introduced the concept of uploading your workouts for the approval/derision of an online community), but this GPS sport watch is a big step forward. Using TomTom technology, it logs your every movement - even sending you motivational messages when you start to flag. You might even go on those promised runs now (or the watch will shout at you). £179.99, store.nike.com/gb/
