Are you asking about any keyboard, or keyboards with Avid keys? I’m working on a PC at the moment, but I am using the current Apple keyboard (the aluminum one that comes with the latest iMacs). I know my settings well enough that I don’t need any icons on the keys. I love the light touch- if I have to use one of the crappy Macally’s in another bay I feel like I have to mash all of the keys all of the time.
The only annoying thing is that the apple key is the start key in windows and every time I miss Option and get the start menu instead I have to wait a few seconds to get focus back to Media Composer. I found a keymap program that is part of a utility bundle you can download from Microsoft. It is supposed for Server 2003 but works in XP pro. I remapped the left Windows button to Control, so it now works the same as Command on the Mac.
