I also agree with your point about poor for businesses, after i reviewed it at home i installed it onto a laptop (dell inspiron 1545) at work to show a few of my colleages, they where impressed with some aspects of it, i had it along side server 8 beta (which has since been renamed to windows server 2012), Windows 8 itself they didnt see it being very practical in a business environment unless it was on a mobile device.
(Microsoft have produce their own high end tablet to go with windows 8, it comes with either an ARM (i thnink) or the Intel processor your choice)
I liked the beta of server 8 it was nice and simple, again with a metro layout but i dont see us taking it up here anytime soon
