The first Android Wear devices launched last week, the LG G Watch and the Samsung Gear Live, Google also announced Android Auto and Android TV.
All of the three new Android based systems from Google will use Google designed user interfaces and apps, and the manufacturers will be able to tweak them slightly, but not replace the user interfaces with their own, which is great news for consumers.
This will allow for uniformity across devices from each manufacturer on each platform, it will also allow for another important thing, which Android does not have on mobiles and tablets, the ability for Google to update these devices with the latest software.
What happens at the moment on Android is that Google releases the latest version of their software, and then it takes the manufacturers months to tweak it to their custom settings, before releasing the update.
This will not happen on Android Wear, Android TV and Android Auto, as Google are looking to have the updates available to each devices on the various platforms at the same time.
This is definitely a step in the right direction for Google, as consumers will be able to buy their devices based on the hardware the need to suit their requirements, and they will not have to worry about the software differences between each device.
