Professor Tools: Whiteboard
Although I love my tech, I need to have an old fashioned whiteboard kicking around. I have always used whiteboards for studying (both in high school and University), organizing my work day, and for teaching impromptu in my office.
I have gone through a number of white boards through the years and finally got the courage to ask for a large whiteboard to cover one wall of my office. IT IS AMAZING!!! The need to write out tasks and to organize plans on a 6 foot by 4 foot writing space just makes me plain happy.
