With proper training, one can type almost at the speed with which one is thinking and that's when you get the true benefits. To put my plan into action I had downloaded a few free tools that taught typing and once I felt comfortable, I started getting my daily news paper to office. I would pick up any random article, open notepad and start typing it. My attempt was to type as much as I could without looking at the keyboard, but only at the news paper and then see how much mistakes I did. The reason to pick the news paper was to basically have new text every day, so I wasn't really typing from my memory.
In time, I feel I became fairly fast. The net effect was that I could write code faster, I could reply to emails faster. While many people appreciated that I would always respond to their emails immediately, some actually made fun of it as well. They would say that I didn't had any work and hence could reply to emails quickly. While on the contrary, since I knew I could type the reply in maybe about a minute, why wait for later, was my motto.
I can now say that I am very comfortable with the QWERTY keyboard and it was hence with some interest that I read about this new keyboard - BeeRaider. On first looks, the layout looks very amusing, but I guess it will be worth a try. I cannot say right now, how easy or difficult it would be learn or if using this keyboard will be any real benefit, but let's wait and watch.
