Good points. Check out the 7.0 branch.

I used calc before and switched away from it because there were many incompatibility issue between browsers. Seems like they have all coalesced for the most part so am giving it another go.

As for preprocessors I am going to be shipping only css and supplying a grid creation tool. There are many forks that offer a pre-precessor du jour offering to complicate your build script with.

Thanks for the feedback!
