The Blue set looks great, I'm probably down for one if the wallet permits. But that backspace bothers me a little - it is the only key to be aligned to the left, compared to the enter and right shift key. Does it look wrong, or is it just me?
Other than that, its nice that there is differentiation between the left and right windows keys, but the lack of differentiation for the right Ctrl Alt keys is another inconsistency.
Home and Printscreen cluster keys are the only ones that are top aligned.
I'm nitpicking, I know - I'll probably get one anyway even if nothing is changed. Although with the alignments slightly out of whack imo, I'll rather take blanks with the same color scheme if they're available. Though I must say that the Enter and Arrow keys are sweeeeeeet.
