Dyson's had a bit of a rough time with companies ripping off its technology and design in recent years, notably with the Vax lawsuit which it (unfairly, in my opinion) lost a couple of months ago. So they're sticking it to China and Vax with a new TV ad, which also acts as a good introduction to anyone familiar with Dyson vacuums.
For what it's worth, I own three Dysons myself (plus their heater) and think they're definitely worth the extra cash. I only wish James Dyson himself was the one rolling around on the floor in the ad, which will be screened on TV from next Monday. [YouTube]
