When Windows 8 launched Microsoft never really produced a compelling set of ads that talked about the product. Looks like Windows 10 is coming out to the same fanfare. This ad, called 'Do' is a perfect example of 'doesn't'.
Doesn't show off the features of the product, doesn't show cool people using the product, doesn't show ordinary people doing cool things with the product.
Its not a bad ad per se, it's just not the right ad.
