Business Insider claims that the smart watch market could be worth as much as 9 billion.
Smart watches have been a hot topic as of late, with the Apple iWatch and Samsung equivalents rumored to hit markets late this year and through 2014.
It's an interesting product category considering nobody is quite sure what the implementation will be like. Google Glass is arguably a more obvious form factor, as it functions like a suped-up Bluetooth headset (with an LCD display).
Will we be talking into our wrists soon, or will will these products just be clones of the Pebble Watch? Google just acquired WIMM, an Android based smart watch company. It shows that Google has not put all its chips on Glass, and might see a future in both form factors. Perhaps they are desperate to diversify because of the whole "Glassholes" term.
