There are lots of things. One that comes immediately to mind is the fact that if you apply any Linux desktop “themes” you are actually pretty likely to end up in situations where certain software is hard to use because they have components or cursors or some weird stuff that was never tested with a variety of desktop themes, so parts of them end up with black text on a #020202 background or buttons drawn with a hardcoded background color or whatever. Since there is no actual cohesive theming environment, the splintered miasma of theming environments means there is effectively none that’s useful. This is, unfortunately, the nature of guerilla software development, and the reason why, as awesome as it is, it’s never taking over the desktop.
