I have been typing on the same keyboard for almost 17 years and I'm so used to it I don't want to go to another kind of keyboard if anything happens to this one.
In fact I have a backup model of the same keyboard since they are so hard to find. It's the old IBM Model M keyboard. I love the sound of the feedback and the racket it makes compared to the newer keyboards. I can't believe how much they are going for on ebay these days!
If you do a lot of typing in your life these are awesome!. I got mine hooked up to my imac however I cannot use the Control-C to copy and Control-V to paste on my keyboard and I have to use the mouse to do those commands, it's worth being hooked up to my mac when I am doing transcription at home once in a while. Do you have a favorite style of keyboard?
