It's funny, I'm an industrial electrician and my smart phone is my handiest tool. I can take pictures from awkward spots like up a pipe behind some bus bars, even thermal, download a manual and keyword search my issues. Video chat with more/less experienced employees to problem solve. Use my phone to trouble shoot cellular issues (m2m iot). Remotely configure network systems. Use OTG cable to serial interface with rs232/485. Scan a barcode of existing hardware,compare it to new hardware and order it online. A LOT of mobile technology is wasted on company's thinking I want this to snap a highlight reel of my weekend and other trivial shit ....When what I really want to do is take a picture with my device, save the location of picture and send it to all parties concerned and document my time.
