windows 8 is particularly bad on a 30 inch monitor when running its native metro apps in full screen with no ability to re-size anything.
this may work great for a 10 inch tablet screen but its a serious problem for any modern professional workstation/content creation setup.
i also had issues (explorer freezing) with my external USB3 drive even for simple things like copying files back and forth. it seems like with each iteration of Windows the basic file copy operation gets slower and slower. all this on hardware that's current. (win7 experience score 7.9)
i'd rather be focused on making cheese instead of figuring out who moved it where.
