IE is certainly making good progress lately.
If IE is making progress in usability, I don't really see it. I typically use Chrome for three reasons:
1. It's fast
2. It has better plugin support (i.e. Adblock)
3. It doesn't have random freezes
Just today I thought I'd give IE 11 another try on my Windows 8.1 system. It wasn't long before I started experiencing weird random freezes that I literally never get in Chrome. Anyone reading my comment history will show that I use a lot of Microsoft technologies (Visual Studio, Windows Phone, etc) but I am frequently left wondering what the heck Microsoft is doing with IE because it's not working.
