I downloaded it just when it was reported everywhere.
Had no problems, installation went smooth, all works fine for me, no weird stuff. But maybe i'll find something when i least expect it

.
Anyway, all those saying "it's not ready for prime time" and stuff, well, a "9.1" version or something will fix that so personally i don't mind. Hmm but Microsoft isn't exactly a company that updates fast when bad things are reported (to say the least

).
