A close shave with technology

I am travelling, and is in a guest house. To my surprise, there is no mirror here, and I need to shave. That's when I got a cue from the woman I saw at the airport, who was using her iPhone to apply lipstick. Today, was my turn to use my ipad as a mirror..to shave. First I tried, Samsung tab3, that did not work due to poor visibility. Ipad did the job of a mirror reasonably well. How true it is, when someone said need is the mother of all innovations. Next time you want to see your face, and if there is no mirror around, use the front camera...:-)
