Adobe is crap as ever, it is ridiculous to have to download so many megabites just to view pdf and it is slow.
Personally, I am using foxit reader even though I have seen threads here saying it won't run under Linux. It works perfectly in Puppy Linux and pretty well in Ubuntu. Copy and paste are a little weird as you sometimes have to select all and cnt -c then cnt-v to paste but it always works somehow. It is fast and almost never crashes, and I think it's good enough for me, maybe you can try to find some in Google, or go to this website cnet.com to find one.
The most powerful one is PDFeditor but the Linux version is super buggy and running under wine is not great either. Actually Open Office Graphics works fairly well save for crashing every 10 minutes or so.
