Dyson as in vacuum? Man, we have had one of those for a couple of years now, I love the thing. But then I have an Ipod touch also, so what do I know?
I actually tend to spend when I buy something. I'd like to think the things I buy will last a good long while, and I'm willing to pay a premium for durability and longevity in general. But when it comes to more disposable things, like food, etc. I have no problem buying store brand.
