My wife and I were at Home Depot yesterday picking up what we needed to build a camping trailer. There was a display with four different brands of drivers, Ryobi (Aack, ptuii, ptuii), Makita, Milwaukee, and Dewalt. The wife went from one to the other, circling around the display, and when she got to the Dewalt she lifted it and asked me why it was so heavy... and I had to tell her that some people think weight makes a tool better and Dewalt makes their tools heavy to appeal to people that don't realize that the weight doesn't make a tool any better. Especially when you can take the tools apart and the mechanical parts aren't any different.
I've owned them all, and the ones I won't buy again are Ryobi and Dewalt. But people that only own Dewalt don't know how good other tools are.
