I must be behind the times, but what is the "+" next to the CD logo representing? I've seen it on a few other newer drive faceplates as well.
On topic: I sure hope Panasonic gets their act together with optical drives. I have an old USB external DVD-RAM of theirs and it's great (relatively) but slow. good burner, etc. They know how to do it right. The 9585 was a massive disappointment (I expected a good burner all-around and great burner on good Japanese media). Maybe the 9587 fixes some of the problems... and maybe they actually do some firmware upgrades to fix problems!
