The much-awaited Google Nexus 5 smartphone has finally arrived, offering the purest Android experience, while granting its owners access to the latest Android 4.4 KitKat OS. Since owners get updates directly from Google, they don't need to wait for hardware OEMs or carriers to release customised updates.

Besides the latest Android OS, the Nexus 5 features 2.23GHz quad-core Snapdragon 800 CPU, 4.95-inch 1920x1080 screen with a pixel density of 445ppi, 8MP rear camera, 1.3MP front shooter and 16/32GB internal storage.

To show the high-quality of videos taken by Nexus 5's camera, Google's first commercial made for the model shows heart-tugging scenes of different kinds of wedding, from a regular bride and groom to an Indian matrimonial rite and even a hint of a same-sex wedding.

Here is the video, titled I Do.

Posted on Nov 1, the commercial boasts of the smartphone's camera that could take great videos despite movement of subjects and pick out the best shorts from a series of wedding photos. In scenes such as weddings and other celebrations, a lot of movement among the large crowd is inevitable, but with the Nexus 5, despite these distractions, it captures moments that really matter.

It brings to mind Google's first advert for the Nexus 7, seen below, which shows a young student's confidence to speak in public being boosted by the tablet.
