Ok, so for a while now, I've been using bad CDs from burning mishaps as coasters. At first, this was great - make use of a piece of plastic that would otehrwise be trhown away, and save wood furniture from water damage. Unfortunately, I've been doing this long enough now, that I find myself unconsiously recognizing any CD sitting data-side up as a coaster - even if that CD happens to be a perfectly good Windows 2000 Pro (pardon the oxymoron there ) CD. Luckily I only set my mug down three or four times before I realized that my coaster was on the other side of my desk....
