Interesting... Its the Pioneer marketing machine at work. Ironically, with everyone using USB drives, there is no need to have an actual CD drive in the unit anymore. Personally, I don't like scrolling through a small screen (its similar to looking at a laptop) so I don't get Oaky's comment about the laptop being a barrier.
I agree that the CDJ-1000 was a pivotal unit in establishing the CD's dominance in the DJ booth. I would equate it as the "1200" of the CD age. No frills, no gimmicks just a like a 1200. I really believe that if you want to see how good a modern DJ is, put them on a set of 1000s.
I only wished that Pioneer would improve the build quality of their top units especially when they charge the insane prices that they do for them.
