Whining about wireless tech is pointless. There is no reason stability would become a hinderance on this device. Wireless technology has been around for so long now it has been refined, sped up, refined more. Short of the wireless chip becoming faulty without any other functionality being affected to bring it to your attention the only bottle neck will be yourself. Speed is fine, wireless networks are heaps fast now, it won't need a super amount of bandwidth! Sounds like a great idea for house parties, but I would imagine that the people would need the APP on their phone, which Pioneer will no doubt put a $ value on - I don't think it'll take off just because of that. Who the fk wants to normally sit around and stare at ya phone when you can stare at your screen. Bit of prep work would be good on the phone though, lunch hours, commuting etc could be done easily - read an article on this from DJ Tech Tools where theres nothing available at the moment to do all your prep work easily/while mobile. I'd love to see one of the companies do this! Thats an APP i'd spend $10-20 on.
