The PC debate can go on and on. Right now it's the iPod (not PC) DJ that's giving me fits.
I have BEEN TO an iPod wedding. By iPod I mean just and iPod and 2 powered speakers, with cable adapters- period. No mixer, nothing. He worked at a PODIUM. His fee was only 750 ( the groom told me ) and he was worth every bit of 50 dollars- hell, make it 75 ( he did carry the two speakers). He started songs-period.
No effects, beat mixing, crossfades, - nothing. He couldn't even change volume unless he walked from speaker to speaker. Announcements were made through a mic mounted on the podium and connected to the house ceiling speakers.
....and before it comes up: NO, the clients were NOT happy, they were livid. Apparently he misrepresented himself.
Can you do an event with an iPod? Sure. Is it a professional presentation? I leave it up to you.
