So for now definitely a good version of IE 8!
Works faster but not as fast as Maxthon.
All sites work as expected.
Even ACID 2 test. Not ACID 3 
But at least something good 
Anyway, without IE7Pro plugin this browser is not usable at all !
MS should think about merging it to the IE.
The security part is very good though. It asks about any strange thing. Well done.
Hopefully the final version will work even faster. I still do not get why opening a tab takes so much time.
Maxthon can open 10 tabs while IE 8 opens 1 tab. (I do not compare to IE7 at all 
)
P.S.
Still no Flash for IE x64 what makes IE x64 useless.
