I just learned about evince, a good PDF viewer for Gnome. It's not perfect, but it's a lot smaller than acroread, and a lot snappier in terms of performance. Here's a ps listing of both evince and acroread, evince is less than half the size:
bhairavi 1 [~] % ps -auwwx | grep evince
sness 1762 12.4 13.3 58564 34020 pts/38 Sl+ 18:40 0:04 evince agile_rails_development.pdf
bhairavi 2 [~] % ps -auwwx | grep acroread
sness 1836 16.4 23.9 123364 61160 pts/38 S+ 18:43 0:03 /usr/local/Adobe/Acrobat7.0/Reader/intellinux/bin/acroread agile_rails_development.pdf
Still, I wish it had a better fullscreen mode, and that when you click with the left mouse button, you can grab and scroll the page like in acroread.
As you can tell, I'm reading my PDF version of Agile Web Development with Rails. I just got the PDF version of the book, and I would highly recommend the book to everyone doing web development.
