let's make it clear. the rubber coating is very nice and makes the keyboard looks cool. it's not a deal breaker nobody won't buy it because of it, but we are talking about a $150+ keyboard meant to last for decades (look at IBM Model M, they still rock after 30 years). If CM wants to produce the "perfect keyboard" has to get rid of the rubber finish because it has NO practical use on a keyboard. it's just a short lasting smokescreen cosmetics.
