I guess I can be resistant to change, but I wholeheartedly agree with the problem of scrolling across light-years of desktop looking for icons is a killer experience. And I constantly open a specific window, such as Control Panel, and look for the program I need whose name I can never remember. So typing in the name of an app I want just cannot work.
Also, I do a lot of video and audio work, so touch-screen isn't an option, much less any under-powered tablet or something. I need to maximize efficiency, not water my PC down to "pretty pictures" that delight casual users only interested in browsing something. I need to get some serious work done, and Metro makes that painful. Someday I may have a device with a touch screen and use Metro just fine, but that will be because I then own something (for some reason) with limited use and applicability for times when I'm not at my computer.
I like what I see so far in Windows 8, but I really need the start menu back. Other than that I'm good to go...
