Apple Wristwatch?

It's quite obvious now that Apple's not Steve Jobs' Apple anymore. It's taken over by Tim Cook and whether that's good or bad for the company will be clear in near future. But the latest rumours are that the company is busy building a wristwatch! It's going to be no wonder that the Apple will have 'siri' embedded in it and will sync with your iphone, imac, ipod and ipad via Apple's cloud services.

So I think your watch will now tell you that you've a new SMS or email or a new tweet. I'm running out of ideas on what kind of innovation will Apple include in their wristwatch. What's your take?
