It should be usable by both a mouse-only, by both a keyboard-only and with a combination of the two.

Accessibility is paramount in and of itself, but it also has the added benefit of helping non-standard situations. Like I occasionally use my desktop over TV from bed with only a mouse, or the reverse, I may only have a keyboard at the time. Or I'm just eating/drinking something.

Gnome performs splendidly here, windows and Mac, much less so.
