I've just installed Windows 8.1 and tested the #internetexplorer
11 Developer Console and I am really surprised.
Apparently Microsoft did a very (very!) good job with this. The #ie11
F12 looks modern, is feature rich like the #chrome
dev console, can simulate GPS and some orientation settings, has performance profilers, network monitors, pretty print and other stuff u liked from the other browsers. It is definitely a good tool for developing web applications.
I will stick with Chrome for Browsing, but it is good to know, that the IE team is doing something about their bad reputation. It's about time.
