For everybody who wants to know what the difference between a KBT Race and a KBT Pure is and what they look like, simply go to
http://www.facebook.com/vortexgear(this is the official Facebook page of Vortex, a company in Taiwan which is having those keyboards manufactured)
You don't have to be logged in to Facebook, their page is viewable without being signed in. Go to their Photo-section and you'll see several picture sets. They're all interesting to check out if you're a keyboard enthusiast, but they have one picture-set for the Pure and one for the Race where you'll be able to see what they look like, what the layout is (no F-row for the Pure, etc.), how big or small the shift, alt, keys are, where the Function-keys are, and so son.
That will probably answer most questions.
