I agree with most of that, but the point about "albeit" (when you think about it, and look at the word closely, the stupidest word in the language) and "prior to" is that they are pretentious. Not only that, they both have perfectly plain and clear alternatives that may be used in every case, namely "though" (or "although" if you like) and "before" respectively. Whenever I see either of these horrors in print I go straight into prize cock red alert.
