TIP: Capturing ideas with your mobile phone

I'm not sure if it is legal, but yesterday I saved myself about twenty pound on reference material for an idea I was developing.  I was interested in gathering visual designs from some magazines that I would never normally read. As I considered whether to buy the magazine for the one or two visual references I wanted, I remembered that I had my mobile phone in my pocket! And so, I quickly whipped it out, used the built-in camera to snap the visual references I wanted, and went on my way. [NOTE: I do not think that my ethics would allow me to do this to copy an article I wanted to read, but my sense of logic seems to allow it for a simple graphical inspiration. What do you think?] This was a real 'Aha!' moment for me about how sometimes I do not make full use of the technology available to me, in the way that can serve me. And that the technology becomes useful when it does work for you. So, the question is...how can you make a piece of technology you own, work for you in a way that was never 'officially' planned?
