Google has introduced Android Wear & gadgets, which is important theme of google io 2014.
Android Wear quickly shows relevant info, watch and phone stay in sync, even swiping.
You can answer phone or sms from watch. Android Wear comes with both square and circular screens.
It has Google Maps for mobile. It can give you turn by turn directions.
And most importantly they are water resistant of course. (To see more details www.android.com/wear/)

But These smart watches as well as all devices running Android Wear only works with smartphones running Android 4.3 or newer, representing less than 24% of all the Android devices on the market today

Google’s LG Watch and Samsung Gear Live available. But i will take some time to be available in Bangladesh.

I am really excited with this astonishing technology made by Google. Waiting to wear it in my hand :D
