Mine is unchanged since I switched from DOS (Borland) to Windows (Visual C++/Visual Studio) development in 1995. If I sat 1995 me down in front of my PC it wouldn't take more than a couple of mins to figure everything out. He'd be confused about all the AI panes on the dev apps, though, I suspect.

(I've also never had a window tiled in my life; every window maximized at all times to avoid noise)
