It certainly does have a lot of features and versatility and I do often seeing it being used - as I mentioned, I still use it and I'm very comfortable using it. My outdated comment is more about some of the features available on other platforms - like Prezi, for example. Your presentations can be made available online so they're searchable (an outreach tool), they have mobile apps so I can quickly pull up a presentation if I'm away from my computer, and they offer analytics - so you know if someone opened your presentation if you send them the link.
If you've seen a Prezi presentation you'll know that it's also pretty different from the a PPT or traditional "slides" presentation - they're a bit more dynamic. I'm not saying it's better or worse - that was part of the reason I wanted to get feedback from others.
