Yes it is trivial, but it really bothered me. Especially since the lcd on a 20D is really small.
the point is that you don't need the screen on the 20d at all really. you have secondary lcd screens for modes and current settings, and you don't need to fidget with custom functions constantly. when shooting, it's fine to make sure you are more or less properly exposing (no black or white frames), and that the framing is ok. you don't need to know how far up her nose little suzy's finger is, or what time the clock on the wall says, those you can check from the confort of your computer. it's an slr, not P&S (aka photo share). some minor dust or scratches on the lcd won't hurt one bit.
