When I was a lurker last year, I remember that there were quite a few topics on the... questionable quality of the CD units. Now that I'm in the market for a notebook, I have taken note of Apple selling refurb 17'' MBPs for only $1999 on the refurb store. I must say, it is a great deal, especially for a computer that went for $2799 up until late last year. The only thing bugging me is the fact that it is a CD unit. Is it safe to buy one, or will I have to be paranoid about it's condition until I stop using it?
