I have never had a problem with any of my trackpads on a single one of my macbook’s, but I have not used one of the brand new “earth friendly” macbook’s, so if you are talking about those, then I am not sure. As for SSHD, they are ridiculously overpriced. The only advantage, if you drop your computer, your hard drive won’t brake, just your screen. They really offer no other advantage (other then you can brag about it.)
