I wasn't really blown away by the RC of windows 8 but it was functional for the most part (i was concerned about not having MC with it but M$ have changed their minds possibly i couldnt confirm on the M$ website) Source
and it certainly was a bit snappier to load on a SSD, my thinking is for a $40 upgrade you cant really go wrong?
other peoples opinions?
seems there is only 2 versions also?
Windows 8 Pro
and
Windows 8 Pro Pack
that later having remote desktop stuff and something else that escapes me atm
