As far as browsers are concerned I tend to be quite pragmatic: I've been using IE until last year because it was the best browser on MacOS (in terms of web page compatibility), but I have switched to Mozilla and Safari quite some time ago and never went back.

While at the beginning there were pages that required me to switch to IE to get their content, I don't recall doing anything similar for a long time now. I almost never open IE, which, by the way, unlike Mozilla and Safari has not got any improvement or new feature for years.

So, as far as I'm concerned, Microsoft dropping IE development is completely irrilevant. Actually, I think that did this quite some time ago.
