I bought an expensive laptop a few years back that had Lightscribe.
I remember thinking it was a brilliant idea and that I'd use it extensively. I bought a load of lightscribe discs, tried it once to check it out - and never ever used it again.
I've never heard anyone else mention lightscribe until your post just now.
Even if you have the software, does anyone make machines that are capable of burning the discs any more?
