For any DJ's out there, how do you think the world of DJing has changed?

I DJ’d for around 7 years before having to sell my Technic 1210’s to buy a mac for producing music. I then noticed the big change from Vinyl to CD’s and having originally planned to return to DJing, i opted out after it had become a CD Deck world. Now it’s all MP3 and i feel the whole DJ scene has been opened up by anyone with a laptop and a download client can play music live.
The Musicians Union used to state that vinyl DJ’s were musicians, but doesn’t state anything for CD/MP3 DJ’s.

I’d like to hear some views on this…
