Dyson, as a company, is only 20 years old, I expect more than that from a vacuum.

Of course, I have a 1957 Kirby, which still works great. Every once in a while I think of replacing it with something modern, but when I go to look everything is undeniably cheezier, and heavier.

The Kirby design has not been updated since the '60s, you can pick up rebuilt ones for just a couple hundred that will live forever. Just be sure to get the paper bag upgrade, dealing with the cloth bag is just unpleasant.
