This weekend, I had fun using Keynote on my iPhone to display a slideshow on the spur of the moment using a Lightning to VGA adapter. Pull iPhone out of pocket, plug into projector, and speak! Just works. So cool.
That adapter works with most projectors, old and new, but this adapter works with any TV or projector that has an HDMI input, and has the added bonus of funnelling audio straight into a TV’s built-in speakers – so you don’t have that extra bunch of wires to plug in.
You can do the exact same thing with an Apple TV, of course, but the likelihood of finding an Apple TV at the place you present at is pretty slim. There’s the option of bringing your own Apple TV instead, but you also have to bring your own Wi-Fi network in order to connect to the Apple TV wirelessly. Still, it’s handy to walk around the stage and swipe to the next slide without marching back to the podium.
(Note the Certified Refurbished link at the right of the top banner. It’s a handy way to find Apple products that look and feel new, come with a new 1-year warranty and 90 days of phone support just like a new product, and a fresh battery, but cost slightly less than a new device.)
