I don't have a 'windows' key. I have a 101-key keyboard that I've been using for over 18 years. Except once. I received a 112 key keyboard at work. Now, you see, I don't 'touch type'. Started working with computers when I was about 12 (in 1980). I always hit the space bar with my right thumb.. on the end.. where the Alt key is on a 112 key keyboard. So I tried the new keyboard, and as a domain admin + software dev, I started typing something and hit space (oops! That was Alt). I just kept typing the next few keystrokes into the menu and nearly deleted a domain.
To end this story, that 112 key keyboard was promptly unplugged and discarded. I have a box of Compaq RT101 keyboards that should last me the rest of my life as long as I can connect them. My fingers also expect a physical gap between the Ctrl and Alt keys, so it is even more of a nuisance to use a keyboard with 'Billy Gates' keys, or what I call 'Billy Keys'.
Makes me a little concerned about what I might need to do if ever I have to use Win8. Hopefully, all this Win8 Metro stuff will have blown over before I have to be concerned about it. I haven't heard anybody raving about how cool Metro is or how much they like the new look of Visual Studio 2012, so I am thinking it isn't going to last.
