Without having watched the videos you mention: I've had that "oh cooool" response to a lot of the mobile / tablet apps, I've never yet had the "wauw, that will be useful to me to create better music" response. Then again I own a normal phone, and no tablet. Maybe a bit more exposure would get me hooked.

@Leigh:
Point taken about the "played on the radio".
In a sense what society thinks about the music I create doesn't really make a difference either: What matters is if it sounds like I want it to. If it does, I'm happy. If it doesn't, then I'll either work on it more, or get frustrated. My experience of touch-interfaces (bar hardware xy controllers) has been pretty frustrating, hence I don't want to use them :)

Making music is the reason that I code, the reason that I use the interfaces I do, to try and achieve my goals. If the interface doesn't support me *creatively*, I'm not going to want to use it. That's actually the reason that I'm not currently using Ableton Live, its workflow doesn't match the way I would like to create music (although it's w/flow is much closer than most other software)

Regarding the predictablity: I don't understand why somebody would use that tool to create the noises they did. So I did assume that the tool isn't providing the output they hoped for. Perhaps I should assume its *exactly* what they wanted. Either way the tool will reproduce the same output given the same input: I'm not doubting the software's capabilites. But I'm talking about interfaces here. Did the user have enough control while interacting to achieve what they wanted? I dont think so, but I could well be wrong.

I'll try get some touchscreen time and see where that takes me :) -Harry
