IE won't die
Am I the only one to have 0 trust in MS to ditch IE ?
Spartan is just a different name aimed at having user-agent not match IE, that's all.
Code base will still be IE. After all, IE 6 to 11 share most of their code, as seen in every patch, every f***ing week, so how will Remdond re-write a full web browser ? Only the UI has changed ...
Funny to see MS being entangled into their own mess (messing up with internet standards for decades) to the point they need another name to dodge the usual user-agent conditionnal code in web sites.
But, yes, we'll see patches for IE 6 to 12 + spartan in all W10 patching sessions.
