We’ve all seen the vacuum cleaner in action somewhere by now. They can suck. But they can’t blow, which I guess is why they came out with the Dyson AM04 Heater/Fan. I got a chance to test one of these bad boys out in Best Buy the other day, and it is cool. You can stick you hand right through it. How many fans will let you do that? The thing that makes this thing even cooler is that it spits out hot AND cold air, so you’re getting something you can use year round, which is nice to know when you’re shelling out a cool (pun intended) $350.
