I previously mentioned my disapproval with smug inventor James Dyson's bladeless fan. Now the temperatures in London are pushing 30+ smug Dyson types are rushing out to buy them. Here's what I have against them.
The big selling point is that it stops "buffeting"; a problem that doesn't actually exist; well done marketing department. It doesn't need to be in the shape of an 'O' - it's an inefficient footprint and again, exists as a marketing gimmick; look a 'fan' without the middle bit! If you're going to draw influence from a traditional design, give the product character, not better-than-thou arrogance.
