    We're serious. Chrome sets the benchmark for running computationally heavy Javascript sites and it also renders SVGs faster than any other browser. Those are the two main criteria for running the 123D Circuits editors so we recommend using it.

    Are you serious? It's like the 1990s all over again except instead of IE it's Google Chrome. Other modern browsers should also be first-class options.
