See attached screenshot. Works correctly in Chrome and Firefox but generates a JavaScript error on Windows 7 Enterprise SP1 running IE11 update 11.0.28.

I've never had a problem that made a switch necessary. However, it seems to have tests implemented, so maybe you have more luck with it.
If you are trying it, I would love to hear your experience.
Our setup is IE11 @ Win7. I don't have a ready sample, but paring down all the Ember and JavaScript libraries we pull in to isolate detectjs for test purposes is definitely the next logical step.
