As of March 16, Ryan Gavin at Microsoft reported that IE9 more than 2.35 Million downloads of IE occurred in the first 24 hours following its release on Monday night, March 14, 2011. He also reports that this works out to 27 downloads every second over that period. Wow!
These numbers represent more than double the download rate for the IE9 Beta upon its release, and quadruple the rate for the IE9 Release Candidate as well.
So far, I’m running IE9 on a single machine in my office (on my HP i7 quad core notebook). I’m still learning how to drive the UI and haven’t quite learned all the ins and outs yet, but I can say I like the more compact layout better than IE8. It also runs perceptibly faster than IE8 does on equivalent hardware. It still doesn’t keep up with the latest Chrome in its support for HTML5, though matters on that front have improved somewhat. I’m going to take this one slow and get to know the program better before I roll it out to all my machines.
