I'd say especially embedded slideshare ones. Just link to the PDF, or I won't read your content (and my browser will probably block it anyway).

I don't know what your product is, but I use four different browsers on a daily basis across three operating systems (it would have been six across 2 if not for the win10 privacy debacle, and even more if I had an android), and I want all my SAAS to work on all of them.

Experience says when they don't work everywhere, IT just dumps the service for another SAAS provider and everyone cheers.
