Google Unveils Android 'Smartwatch' to Make Checking Your Phone Even Easier
Google unveiled its new Android smartwatch at its annual I/O developers conference in San Francisco. The device, part of the tech giant’s Android Wear product line, will quickly show customers weather, traffic, email, shipping and travel updates.
According to Google, Android users check their phones an average of 125 times a day.
