A review with not much research is still a valid review - namely on what even somewhat technically savvy users aren't able to intuitively find out about Windows 8 usage. See also the inability to close metro/new-style/whatever apps. I didn't find that out myself when I tried Win8 for 10min or so. And it's not like killing those apps isn't necessary like on iOS, since the behavior changes when they are open, i.e. Windows button doesn't switch to Desktop anymore.
