Your using the Release candidate version 7.0.5700.6 pureblood, from what I remember
The Final release is still up and coming, I can't see it being much different than what your using right now
But probably some bug fixes
Although I don't use IE all that often, looks like some nice changes
I would Update when final release comes out
P.S. I hope you use the IE View extension in Firefox, makes it easy to switch from firefox to IE
Oh, and thanks for all the News updates Josetann
