Nothing really new here, TBH. IE is still being used by fanboys (such as myself) and, of course, those who still (somehow) have no idea that there is competition. The latter, however, is growing smaller in numbers day by day. I used to troubleshoot people's PC problems only to get a herpy derp response when asking which browser do they used or do they have alternatives to IE.
Nowadays people have approximately 1-2 additional browsers they either have no idea how it got installed (like Chrome being offered through Avast installation) or tried to use it and just kept it on the PC while still preferring IE.
