No they won't, LOL. I'm a DJ, and I can easily identify a lot of problems with this device being one of if not the most tacky and unprofessional device yet to come out 'for DJs'
1) I really doubt that screen's accuracy will be any decent to do any kind of detailed navigation without first having blood boil
2) speaking of navigation, it looks extremely limited, hardly professional at all, its missing many key features.
3) the ipad maxes out at 32gb storage capacity for a ridiculous price. at that point you may as get a netbook for 1/3 the price and get 4X the capacity to store a library of mp3s
4) would the ipad or this application even recognize a flash drive/usb HDD connected to it to browse through extra music?
and lastly and above all else, since this is a self proclaimed PROFESSIONAL product, given apples amazing track record in regards to SOUND QUALITY, the ipod, the iphone, the ipod hifi, this is destined for FAIL. Apple's been known for very poor sound quality, and the iPad is not at all likely to be any better than any other portable device apple has ever released.
I laugh at news like this, I also get a real good kick out of it too.
"Professional".......LOL
The iPad maxes out at 64gb, not 32. Plenty of music for a night at the club or a wedding.
