A while back I was looking to buy one of the official devices that go in your wriste but only seem to be available in america, this is a great idea if it works, thank you.

on one note, for health & safety reasons I would highly recommend you turn wifi off, turn bluetooth off & set the phone mode to tablet mode...

Even then, I think having eletrical power next to your body might not be very healthy, if you ever study thai chi or some other similar accient martial art, then you should know what i meant, but then such people probably would not even own a mobile phone

either way thank you
