I had a need to scan a document today. Nothing too tricky about that, except that it meant finding the scanner, turning it on, running a program, etc etc.
Too much like work.
Then I remembered I had Office Lens on my phone. It's awesome. Point the camera at a page of text and it works out where the edges are, takes a picture, tidies it up and then offers to share it just about anywhere, including on my One Drive disk as a pdf file.
If you've not got this on your phone you're missing out.
