I think it's a great question. When I think about why I don't use pgp personally, and why I don't encourage others to use it (besides the fact that no else uses it) it's a functionality issue. I need to be able to access my email via my computer, phone, AND web browser (potentially not on a computer I own/control). My understanding is that is not easy to accomplish - maybe I've been misinformed. Until then, it's hard to start using pgp. To answer your question, a good place to start might be a company like Good Technology - given their involvement in email solutions for so many large corporate customers.
