Line up, suckers. Invention and innovation isn’t reserved for sexy handsets. Sometimes it’s used to build the better DadVac, like Dyson’s all new Cyclone V10 cordless vacuum I saw yesterday. It’s got a tiny, 125 gram motor that spins at a blazing 125,000 rpm and, according to Dyson, has as much suction as a plug-in upright. I gave it a quick test-drive and came away impressed, even if it is $499. Speaking of uprights, company CEO and inventor James Dyson announced that the company is done “inventing” new plug-in models. It’s all batteries, all the time from now on.
