I think also that Dyson is able to comfortably feed off the back of the current trend nay fever for constantly replacing "technology" fueled goods. Never in my lifetime have I seen such a frenzied attempt to change and upgrade anything. We have of course always had yearnings for things and a constant thirst to buy the latest, but I don't ever remember it being a practical reality in quite the way it is now.
If the recent explosion of computer and mobile phone technology had not occurred, I think the sales of new Dyson models would be much, much slimmer.
