I'm so glad Internet Explorer/Edge/Trident is Officially Over. If you told me in 2010 that in 10 years the worst browser I'd have to support was Safari/Webkit... I'd be overjoyed.
One thing (only thing?) I honestly miss about IE5.5-8 is how amenable the engine was to polyfilling. It wasn't fast, but you could do almost anything with the right polyfill technique.
No sessionStorage? Use window.name. No (then-) modern CSS? Use CSS3PIE [0]. IE doesn't support the transform CSS property? Use an *.htc behavior to convert the transform to a matrix filter.
It was madness, and it was beautiful in a Cthulhu kind of way.
