No, Edge is a very different, re-written browser, much more standards-compliant and frankly, one hell of a lot better than IE. It looks like it's going to be a great browser.
I predict it will do well, because it's good. IE has had its death warrant signed -- the only holdouts will be businesses that were silly enough to write big applications that require IE.
And I for one am overjoyed by this.
One of the most annoying things I've run into in the corporate world are poorly written websites that will only work with IE. Not only that, they tend to work with only specific versions of IE. I can't tell you how many headaches this has given me.
This is going to force some of those things that is going to finally force them to fix these broken apps. Thankfully, they are getting to be fewer and fewer as time goes on. However, for some corporations, they are going to have issues upgrading until those apps can be fixed, because as far as I know, there is no way to install a standalone copy of IE on an upgraded system.
Serves them right IMO.
I'll be interested in seeing if MS has managed to finally build a browser that isn't swiss cheese as far as vulnerabilities are concerned. From what I understand, they've finally abandoned active-x (which is where a hell of a lot of those vulnerabilities were coming from) That's a really good thing, because it's also the active-x stuff that was what was making websites IE-only.
