Granted, you're likely not going to run into situations where you're dealing with large number of files, but that's a situation where using the command line and being familiar with arcane commans would be faster. Had one customer balk at my suggestion of command line when he had to deal with a situation where there were many tends of thousands of files in a single directory -- his response was "This is the 21st century, it's Window NOT DOS!". He shut up after I dealt with the situation in less than a minute through the command line -- something that he had one of his staff dealing with for over an hour and barely making a dent in it.

Trying to find something in Control Panel is was hard enough. Category view in Vista made things even harder. Also, some things got changed slightly (was it "Time & Date" or was it "Date & Time"?) -- so simetimes Classic View didn't help much either. Pop into search box "Time" or "Date" and you'll find the proper Control Panel item pretty quickly.

On those occasions where you needed to set up an ODBC data source for a 32-bit program... Don't know about you, but I find popping into search, then typing C:\WIN -- then locating the :"c:\windows\" item, then continuing with SysW - then selecting c:\windows\syswow64\, then entering ODBCA then selecting c:\windows\syswow64\odbcad32" often faster and easier than having to navigate through Explorer (usually because you run into those occasional barriers that Windows likes to throw in your way in the attempt to protect the user from doing stupid things -- mainly things like not immediately allowing you to view root directory of c:, then not immediately allowing you to view the windows folder, then the system sub-folders, etc.). Okay, so it might be easy enough for you to do this yourself while navigating the GUI -- just try walking a customer over the phone with this process. Trying to get a user to navigate the GUI gets really hard when there are more than a handful of items to navigate through. Clicking on search is often faster and easier in this case.

Okay, so all this isn't specifrically Win8, but there are situations where typing may not be as obvious as point and click, but certainly easier and faster.
