Couldn't agree more. Thing is, I already spend thousands of hours to learn the querty layout. ( And qwerz layout, but thats not very different for the argument.) To gain any advantage from another layout, I would need to spend hundreds of hours, for at best minimal gain. Additionally, I wonder how these decisions are made at the manufacturers. I would assume that most engineers there can touch type and should therefore have precisely the problems with the keyboards that the article mentions. So why don't they notice?
