I think most of us can agree that IE 10 has come along way. The reason web developers hate IE is when we have to build sites for older versions of IE because people can't or won't upgrade. Sometimes clients require support for these older browsers. I have no problems with IE 10, but those older versions that just won't die are the problem.
It's more than that. Here are some features that other browsers have that IE10 still doesn't have:
* SPDY (supported by Firefox, Opera and Chrome)
* FlexBox (partially supported in IE10, FF and Safari, full support in Chrome and Opera)
* WebGL (partial support in FF, Opera and Safari, full support in Chrome)
* Shared WebWorkers (fully supported in Chrome, Safari, Opera [even BB browser...])
* File API (partial support, full support in FF, Chrome, Safari, Opera [also BB browser...])
* WebM/Ogg (fullly supported in FF, Chrome, Opera)
There are a few things that IE10 has that other browsers don't have yet, but knowing M$, this is likely the last update for a year or so. I expect FF and Opera to catch up soon in those places where they lag behind.
Sure, IE10 isn't that bad, but there are still some things that can't be used yet that developers (like myself) really want (especially a unified video format...).

It's not just older versions of IE that we dislike developing for. It's been the current version of IE at the time that has always given me headaches as well. At this point, it's comical to me how backwards and standards-incompliant every subsequent release of the browser has been over the years. I share milesf's distrust.
