First, I hate the changes they've made to the UI. Not attractive or intuitive. I can live with that, though. My biggest gripe is that it's as slow as an arthritic snail. I'm running virtually no other apps (Mail, FireFox, iTunes) on a dual 2.5 G5 with 3.5 gigs of RAM and Acrobat is S-L-O-W. I've got a single, 1.1 meg PDF open and I'm using the measuring tools on it. I have to wait for the screen to move in ragged, jerky fits and starts and the act of drawing perimeters or areas for measurement is agonizing. Oh, and it's crashed on me, too. Not extremely frequently, just enough to be really, really annoying. All in all, I'm not impressed with Acroscat 8. Oh, yeah, and what's with the keyboard shortcuts for the magnifier glass? Sometimes they work, sometimes they don't.
