Your sarcasm doesn't acknowledge iPaper's potential. PDFs are actually somewhat annoying to open for many people. Scribd's platform independent solution is actually pretty cool.
I can't vouch for Foxit, but viewing PDFs through Evince is also far more efficient in terms of processor usage, especially since flash seems to like to take up all the cycles it can get.
I say add an extra link or make it a cookie preference, so I can have different settings depending on where I am.
