Use Marker Boards for your notes

We got these great 4" x 8" marker boards from a rep (Idea Paint) and I thought wow, this is great for greening up the office or near the phone in your house!  Just put this and a reusable non-toxic marker near your phone and take your days notes on that instead, you can then just erase your notes as you complete them and reuse, no wasted paper. I love it. Now obviously some notes have to go into project files, so my plan is here to either type the notes from the board into a word doc and save electronically or use my pad of recycled paper from the misprints bin in the copier room to take those notes that need to be filed.  You could also use chalk boards, but chalk scratching while on the phone may not be ideal for a work scenario, maybe better at home.
