NO! IE is still there but you have to look for it.
Windows weekly on This Week In Tech has covered this extensively.
Leo Laport, Mary Jo Foley and Paul Thurrott do a podcast Wednesday nights. You might recall the old G4 TV channel The Screensavers. When that went down Leo formed his own company that pretty much the same thing. twit.tv. It’s a great source of tech info.
OK, it didn't disappear, it went into hiding.
Spartan/Edge is front and center. I think it's faster and a bit more stable. IE would lock up occasionally on that NOAA live weather site.
Not having a copy of 10 yet, I was going by some tech blogs stating it in the same way I put it. One can assume they kept it for some reason...perhaps for enterprise customers and those with IE based whatevers...apps etc..
But it seems clear to me that the intent is to totally replace it, due to it’s gross weight, with a new lighter, faster build.
