Microsoft should give up entirely on Internet browser development. I cannot see any good reason to throw their money away like this. They are a company too dependant on legacy software to bother competing with Google and Mozilla. Cloud services seem to be their brightest modern opportunity, but they really weren't prepared for the 2010's. Competing with Chrome is just chasing cars. Of course they've always had the advantage of being the default browser. I still don't think average users will ever see IE as anymore than a fly on a Window. Regardless of who's layout engine theyre forking.
