Well, if they improved the one in OS2008 enough, that would be nice. I'm tired of the browsing issue too.
But why (I consider) it's much better than OS2007 version:

Evince lets me:

• view 2 facing pages
• view continuous scrolling
• rotate (for portrait view)
• use the TOC in many PDFs, instead of memorizing page numbers
• easily go to page numbers (w/o menu)

And I'm happy to trade browser integration for all that. My main use is offline reading of course notes, manuals, exported PowerPoint presentations, etc., so it's not a big deal to save the odd online PDF, view it, and then delete it manually.
