Technically, Shutdown is an application - shockingly titled shutdown.exe - It also has its own GUI and can be accessed for greater control from the command line. So yeah, even when that little button on the taskbar said Start, it made sense. When you click on shutdown, you are starting the shutdown application (shutdown.exe), the same is true for logging off (logoff.exe) and restart is controlled by the shutdown.exe application. Shutdown isn't a setting. Settings are things like colour count, resolution, UAC level, etc. Shutting down, like restarting and logging-off, are tasks.
If you'd like to check this out for yourself, shutdown.exe can be found in C:\Windows\System32. If you type shutdown /? into the command line, you'll see the available options for it and if you type shutdown.exe -i, you'll bring up the GUI for the application.
Do I really need to answer this or did you just put no thought into that response? Ask yourself a couple of questions - Why are Apple doing quite well without having the enterprise market? Why couldn't Microsoft do as well without the enterprise market? Hint: The answer to the second question lies in the answer to the first.
Metro - forced to have clutter. Traditional Desktop - Right-click > View > Uncheck 'Show Desktop Icons' > No clutter.
How many of us have a laptop with a touchscreen? They're too new and expensive and pointless to buy right now when we have cheaper, traditional alternatives. I think we all agree that as far as touchscreens go, Windows 8 will be fine, if not just serviceable. For traditional laptops however, it's going to be as irritating as with a traditional desktop. Hell, touchpads are already finicky enough without expecting users to learn the lumbago with their fingers.
I think you mean that you can explain it easily by saying "mouse over the bottom right or top right corners of your screen, and then move the mouse towards the icons on the right side of your screen. The charms menu will appear. Click the Settings charm when the charms bar appears. Click the power button at the bottom of the Settings pane and select Shut down to shut down." That's a big difference to "Click the start/windows icon to open a menu. Click the shutdown button"
