Is there any way to view a PDF in Preview in Full Screen? Quick Look works, but it doesn't have the 'remembering the page you were looking at' feature that I like.
Slideshow (or Shift+Command+F).
Install MegaZoomer, it'll give you nice fullscreen viewing in Preview.
Update: Note that OS X Lion will give you this feature.
by using this combination, you can also zoom in pages in fullscreen.
