The only problem I have with statistics like this is that the figures can vary massively depending on the source, so in practice I think the best strategy is to look at your own web stats and decide what is important.
The new Edge browser seems like an improvement, so perhaps Microsoft is learning.
So far my experience of Edge is fairly positive, having tested it on various sites. It’s fast with a clean interface and not causing big headaches when designing like the old IE browsers. I don’t think it supports Woff2 fonts yet but it’s generally a worthwhile improvement on IE.
