Hey OzBargain, wondering what's your opinion on the erasable paper/notebooks?
Do you prefer them because of environmental benefits or you hate the pain of erasing ink from paper, spending extra $$ of the erasable ink pens which cost way more than the standard ball point pens, (essentially make up for the savings you made using only 1 notebook for a period of time).
There is no doubt that in the long run both ways cost exactly the same in my opinion, but one is more gear towards environmental care, while other one gear towards ease of throw old and get a fresh one.
CDs are better
