IE9 has made some nice improvements, but I also ask myself why it still lags behind in so many ways. For example, if I were writing this comment in IE9, I would not be able to see what spelling errors I made. It's 2011, and IE still does not have spell checking on text elements. The IE9 GUI has also become unresponsive for me for double digit seconds several times. There are literally dozens of little annoyances like these. How these glaring issues continue to exist really is a good question. I think some of the other posts on this subject probably hit the nail on the head: Microsoft doesn't want the browser too good (since replacing native apps with web apps helps out competing operating systems), but at the same time, can't allow their browser to get too far behind, because with or without Microsoft's blessing, the web has made huge market advances. Thus, they kind of catch up, making their browser just barely good enough for most people, but always fairly mediocre. It's the only reasonable explanation I can think of.
