Thanks for highlighting these various annoyances! I strongly agree that it's poor product management; bad for the Apple brand, *especially* among its dedicated, long-time users. (:-( Even if the latest apps didn't support legacy file formats (come on, Apple, how much app overhead versus how much user time and goodwill wasted on screwing around manually reformatting files?), there could be a drag-and-drop batch-update (AppleScript/Automator) utility to manually convert files (with helpful option to keep original file timestamps).
