I can't say I like GoMac very much. I never cared for the Windows 95 Start menu. The Start menu just looked like a cheap clone of the Apple menu. The buttons are nice, but there's not a huge need of them on Macs. The application menu does a good job of organizing programs.
Do you use Kaleidoscope? I think that's pretty nice, but I don't use it just because I want to cut down on extensions/control panels.
