Hah, I got one of these about a month ago. I absolutely love it. I think my typing speed has increased significantly. I also got the “ultimate” model (no markings on the keys!) which aside from flummoxing lots people who try to sit down at my desk and looking really cool it also improved my typing, mostly of the punctuation keys. !#$% etc since I can’t “fall back” on the markings for the rarely used keys among these.
