Yes, and yes.  Adobe recently released an update of Acrobat for Linux
(for a long time they hadn't gone beyond V5; recently they released V7
which I believe is the current version).  I've used both on my Linux
(Fedora 1) system.  Both work, though V7 is clearly better.  That
includes some things I run into at work that other viewers don't
handle -- such as password-protected files.
