Innovative DAW for iPad?

[musicplanet]

I see iPad as an awesome music idea capture tool. I am glad that there has been some awesome product development in the past both in instruments (e.g., Korg series, Animoog, etc.) and DAW (e.g., Nanostudio, Beatmaker 2, Cubasis).

Now, I don't want to use DAW which mimics PC's DAW, such as Nanostudio and Beatmaker 2. While it may feel at home for first use, I think its interface is not best optimized for iPad. I want something that's innovative for iPad. I really like Propellerhead Figure and Thumbjam. I think they both are very innovative and optimized well for the device. But I feel that they are not a full featured DAW in power department. I also like Garageband, which is more resembles traditional DAW with great features (and price hard to beat!)

What would you recommend for an innovative DAW for iPad? Maybe something like Ableton would work well for iPad, if there's such app.
