One issue with GUI's is that you're sometimes stuck telling someone how to use a GUI that you didn't develop, for instance having a user manipulate settings in the device manager, which was created by Microsoft.

One thing that's rapidly improving on the command line side is Search. On my modern Windows computers (8 and 10), I don't search for things by hand in the dialogs any more. I press the Start button and start typing text.

For instance, Start plus "device manager" brings up the device manager, whereas I have no idea how to find it in the menus.
