I can think of one use (a whole 1!): Exercise. If you want to listen to your tunes as you go jogging, you've got several options currently: waistband (eurgh), in your pocket (eurgh + broken phone when it eventually falls out), in your backpack (eurgh) or strapped on to your arm¹ like you are some kind of cyborg (actually, I kind of fancy being some kind of cyborg).
A touch sensitive watch that beams my cheesy 90s eurodance to my headphones would be dead neat. Plus, it would actually be in a place that you can look at and touch, so you don't look like a wally trying to prod your arm because you've somehow put "Scooter" on repeat.
Not sure it is £200 worth of dead neat though.
¹ Interestingly, I was going for the anatomically pedantically correct definition of the "upper arm" (this is The Register after all). Turns out it is "arm" - the bit below the elbow apparently is not part of your arm, but your "forearm". Who knew?
