Not just in terms of how pretty your slides look, but also in terms of whether the data you’re presenting is actually properly legible. A good clear font is really important here. Unfortunately, far too many fonts are appallingly bad if you’re trying to tell certain characters apart. Imagine if you’re at the back of a room, trying to read information on a slide that’s (typically) too small and (if you’re unlucky) the presenter’s speech is also unclear to you (noisy room, bad audio, different language).
