Each time I travel to the office by tube, I'm irritated, amused and confused by the posters on the escalator which are part of this advertising campaign.

I know that Microsoft have always sold their latest version by denigrating the previous one, but this campaign also insults their own customers.

Anyway, the main thing the campaign does for me is just to associate the two ideas 'Microsoft' and 'dinosaur': probably not what was intended.
