As a reader? Preview all the way
Acrobat Pro has some more advanced features in creating PDF's but for reading and manipulation, Preview should be all you need. It is very quick and versatile and does a lot more than most people realize.
wow. thanks for heads-up. But is it true that I can convert most formats into PDF on a mac by "printing to PDF"?
So what can acrobat do that preview can't? What sort of advanced PDF features that Preview lack?
