Electric Air Dusters Rock

So... I can see using this to dislodge dust from crevices, but isn't the solution to widespread household dust to vacuum it? The point of a compressed air can is the point impact (to borrow a term from other power tools). If this device isn't capable of doing that, aren't you better off with strong suction?

Something about this piece seemed confusing. Reading articles about high-end vacuum cleaners, a major focus is sucking up dust without causing ancillary dust clouds. In this article the author seemed to be reveling in it?
