The Braille Notch!!

Another advantage you left out that your style has is the braille like notch on the F key that lets you feel where "home" is. Which is one of the missing deal breaking features on a lot of the special hand sized keypads dedicated to gamers. It would be so cheap to implement strategically placed home notches on their products. Sometimes i think WTF!!! what there they thinking. I think one biggest hurdles anyone would have moving from style to style is learning new finger muscle memory.
