It seems like everything electronic has a touch screen now, but if you ask me there’s just no replacing a nice, physical button to get the job done. Take the iPhone/iPad, for example. When you use the camera app, you get a little shutter button at the bottom of the screen.
Press it, and *snap* – you’ve got yourself a picture. Easy, right?
But did you know the volume up button also releases the shutter? It’s much easier to reach, too!
…and if you have a pair of Apple headphones hooked up, you can use the volume up button on those to snap a picture as well!
