Whiteboard drawings
I like this hack from 43folders wiki. A friend suggested this to me as the biggest advantage of having a camera as part of your phone. He said so in response to my rant about how they put camera into everything and I just don’t take that many photos. But, I have to admit this is a good use of the cam in your pda or phone.
* To save the contents of a whiteboard before erasing it, take a photo of it with your digital camera. If the diagram is nice enough you can just upload the photo to your wiki.
There is something about a whiteboard to get the creative juices flowing in a meeting or even being able to communicate a complicated concept. So, start snapping away at the end of your meetings.
