Hey all, I recently purchased a 12" MacBook. Everything has been fine, but from what I understand the keyboard on this model of MacBook is less than robust. I'm thinking of returning this MacBook due to the apparent prevalence of the issue. I wanted to get a feel for what owners in this community have experienced. How many people here have had a MacBook, say, since launch that have had no problems with their keyboard? Should I be worried enough to return this machine for the 13" MacBook Pro? What's the consensus ?
