This time around MS did it right with IE10 - however they fucked it up with Windows 8 (on which it runs) really badly. Hopefully the version for windows 7 will be released sooner rather than later.
They mixed mobile and desktop approach within the same OS. Time will tell, but I'm not betting on it. I may be wrong though.
I've been using it on my main workstation for the past few weeks and I think they did a great job.
EDIT: Oh, I forgot to mention...it's not perfect (oh noes!!)
