In my opinion, Windows 8 will never be fully accepted until they either allow the complete removal of metro, or allow considerable more control. If you have Win 8 at home, with live tiles running, take a look at your router logs and note the massive increase in traffic. Now imagine your 200 employees suddenly all using live tiles. That's a lot of data flying over your network for basically meaningless information.
Second, the only metro apps worth anything are the ones that come with the OS. MS needs a quality control method in place prior to publishing these. Either they are broken, barely functional, or take forever to load. I haven't found one app worth keeping, let alone purchasing.
I have a 2-in-1 transformer laptop and while undocked, I use desktop mode 99% of the time. That 1% is viewing the OS' built in apps (news/weather/sports), which I often refer to as "idiot mode time" as it takes basically no brain activity to run....but maybe that's MS' goal all along.
