I don't think I'll bother upgrading just to get the keys with no lettering on the top. I've got a whole box full of compact keyboards that I bought and didn't like, but the CMStorm is probably my favorite PC purchase of the last 3-4 years. I think I've got the blue switches and they're just about perfect for gaming and typing. The only thing that could make the board better would be if the switches were as easily changeable as the keys. It'd be nice to swap in some browns for the WASD keys some weekends.
If the keys are lit by LEDs, then it seems like a pretty sweet feature to place the labels where they are. If not, then it's gonna be damn hard to game/type in the dark! 😛
