RoboHornet is browser benchmark that comes from a mixture of organisations that wanted a way to benchmark browsers in a more real world manner. Currently it has JSPerf, YUI, Google, Facebook, and others contributing to it.
It seems to run happily on desktops, laptops and mobile devices.
So, benchmark away! If you have a dual boot system, it'll be interesting to see what differences that can make. Where possible, take a screenshot or picture showing the results, and note the platform it is running on. That would include the device/computer specs, the OS, and the browser.
