There are a couple of iPhone apps in the App Store that act as PowerPoint remotes and offer an Apple Watch app as well. If you want to control a Mac or PC presentation with an Apple Watch, well, that's trickier. But if you don't want to invest in that $49 adapter and start presenting from an iPhone, the Apple Watch app will be of little use to you. The two stay connected all the time, something I never experienced in the two years using a Pebble.

On the stability side, that's probably a win-in my two weeks with Apple Watch, I've found its connection to the iPhone to be rock solid. The app is built to control PowerPoint running on the iPhone, not on a Mac or PC. Force touching the screen brings up a menu with two options, to restart the presentation or end the presentation. Microsoft has designed the PowerPoint watch app with large Next button and a smaller Previous button, along with a running clock of the presentation. With those caveats out of the way, though, the PowerPoint app for Apple Watch looks clever. That's a lot of opportunity for failure, and in my experience the failures happen often enough that I usually don't even try anymore. But one hiccup in the wireless connection between the two devices, or the software running on either device, and the jig is up. You'd think that an iPhone would make a great remote for a presentation, and you'd be right! Using my phone as a remote allows me to roam the stage or conference room while advancing slides and reading presenter notes. This is the problem with using my iPhone or iPad as a remote for my presentations, too. But if I'm using an AppleTV to display my presentation on a screen via Apple's AirPlay technology, I'm now relying on the Mac, the AppleTV, and the reliability of the wireless connection between them. If my Mac fails, my presentation fails, sure. The more devices you rely on to execute a presentation, the more opportunity there is for failure. I should probably remedy this-though I'm not thrilled about paying $49 for a Lightning to VGA adapter-but in the meantime, my Mac is the only device I own that I can reliably hook directly to a projector. I have all the video adapters for my MacBook Air, and none for my iPhone or iPad. I usually end up pressing buttons on my Mac keyboard for a couple of reasons: cables and reliability. When I give presentations these days, I can never decide how I want to control the slides.

With PowerPoint, Microsoft isn't suggesting that you'll give people tiny presentations on your wrist (though that would be really funny), but that you'll use the Apple Watch as a remote control.

It makes sense-Word and Excel don't seem like naturals for your wrist, unlike OneNote. The second Microsoft iOS app to add support for Apple Watch was PowerPoint.
