Those iPad stands are very rugged and professional looking. It looks like they're probably the Gooseneck iPad stand developed by arktisdistribution at a cost of £139 from amazon. (Thanks for the link Gábor!).
As a follow-up to my previous post, here's a quote from Stereomusik regarding the changeover to the new Red Bull BPM DJ app;
"After one year in the App Store, we made the decision to continue with Red Bull as a partner and build further the Red Bull BPM platform. We made some changes to make sure we have a business model that would work in the future. In-app purchases offer an easier, much more flexible purchasing path and reduce piracy.
Together with Red Bull we made the (not easy) decision to replace the current HD and Pro apps, for the new universal Red Bull BPM DJ app."
