What does Adobe Reader do? Displays PDF pages. How does it do it? With as much bloody-minded bureaucracy, delay and needless interaction as possible. Perhaps it's because we humans have been spoiled by books, where the gap between wanting to read something and reading it is as short as the time taken to lift the cover. But Reader's incessant updates (demanding you reset your computer — why?), thundering great list of modules to load, and hour-glass-provoking pauses for thought have given Portable Document Format a reputation for being as welcome as a flatulent camel in the kitchen.
Which is a shame, because other lightweight PDF readers seem to manage perfectly well.
