When I got my new computer, I noticed — oops! — Nero (my usual CD burning application) wasn’t preinstalled. And when I tried popping my disc (I think it was Nero 6 or so) in, it didn’t cooperate with Vista, and the Nero site just told me to upgrade.
So until I got my hands on a copy (thanks to the tech at a local store), I was using CDBurnerXP. It’s a good program — not difficult to use, and I didn’t get an expensive coaster (yet).
