1. Google's ads are usually made by Creative Lab and this is not at all their style. Or the style of any other Google ad. It bears more resemblance to an Apple ad than a Google one.
2. A laptop "completely designed by Google" might be something that its fans want, but I doubt Google would ever say something like this in an ad and risk antagonizing its hardware partners.
3. Speaking of hardware partners -- who made this? Even when Google makes Nexus devices the manufacturer's logo is quite prominently displayed. Again, I doubt Google wishes to finance a non-partnered piece of hardware.
4. Also, yes, touchscreens are on laptops are stupid. This is a stupid idea.
My bet is that this is the final project of some kind or a demo video from some upstart ad company that wants to show what it can do.
