I'm not sure what you mean by pdf being simpler, charliex.. Pdf is already rip'ed which means you get true wysiwyg. Postscript can look different depending on the rip, especially for colour prints.
I use Latex-dvips-ps2pdf or distiller a lot, and I've yet to see that a pdf becomes bigger than ps. A bitmap in ps is
huge. In pdf I can easily change between print-settings or settings for online viewing, where the online setting can produce very small files with downsampled jpeg images.
For viewing and printing papers with text and equations, I haven't found a good alternative to pdf. I use gsview for viewing ps, where I get an ugly screen appearance
Pdf has nice anti-aliasing for embedded fonts. And then you can get links, bookmarks of indexes, reviewing, signatures and simple editing. I've never had a problem with stability on either Windows or *nix. I'm not too happy with the latest version of Acrobat though.. as with most other software, it's becoming bigger and more memory hungry for each new release.
