My latest attempt at reducing friction has been to buy a Wacom graphics tablet to see if that helps with diagramming. I don't miss my old Tosh m400 much, but sometimes I wish I had a tablet to hand for simple drawing.

Anyway, other "friction reducers" that I'm liking at the moment:

• Adding Wikipedia to Windows Vista Search
• Sheer Post-it notes (of course!!)
• Chalkboard for your laptop - this is for Mac, but I assume it's cross-platform compatible.
