Advice needed: my boss wants all text in the company's PowerPoint presentations to be in Arial, no exceptions. How serious is this?

I'm no design expert, so I'm hoping to get some perspective from you guys on the importance of fonts. I'm aware that the common wisdom is to use a complementary pair of fonts: one serifed, and one sans-serif. But would it be a serious flaw to have all text (title and body) to be the same font, or is not something most people viewing a presentation would care about? For context, this is a finance company, and the audience would be people looking at charts and stats and ad copy about market indexes.

Basically, if this is the kind of thing that would make a lot of people snort at our presentations, then I should try to convince my boss to allow a second font; if it's not, then I'd just as soon let it slide. Thanks for your advice!
