Same. The lighter gray 2000 uses compared to 9x is also much more pleasant.
It might sound ridiculous but using 9x with the default theme felt a bit depressing. It conjures images of being stuck in a building with that awful fluorescent overhead lighting on a day where it’s dark and dreary outside.
2000 on the other hand is about as refreshing as a gray 3D beveled OS theme can look, on par with Mac OS platinum and maybe slightly edged out by the bright colorful sunny tab titlebars of BeOS.
