Apple's Next Thingy

Don't really like to use the word "thingy" but I wouldn't know how else to describe this piece of pleasant rumour of Apple's next product that I've learnt about via John Gruber's Daring Fireball site:

To be more specific, Apple is looking to launch a smart band towards the end of this year whose collection of sensors will be able to be used not only to monitor the activity of the wearer, but also to operate other devices as a gestural controller.

Gestural band!? I like this idea of people moving their arms in mid air which will surely appear totally weird to the observer. If true, this is going to kick all the smart watches and bands' asses out there! Woooohooooo!!!
