280 Slides: PowerPoint made fast and easy, online

I can only see 3 reasons why you would:
- Cost, though most people pirate PPT/Keynote anyway and big companies can afford it.
- For people who don't use Mac or Windows or who switch to random computers a lot.
- Multi-user editing at the same time on the same presentation.
That seems to be a real minority of users though, and for just about every other reason, PowerPoint and Keynote trouce these web-based implementations. Even basic presentations are faster and easier to make and look nicer in a native app. For power users, it's no contest.
Is there something I'm not getting?
Behind-the-scenes version control is in Google Docs, so I'd expect it to be in their presentation app, too. That can be really handy, as well, and while you can do versioning decently in Powerpoint, I don't think may people use it.
