Portable Music Creation Studio for the iPhone/iPod

The first time that I saw the Pocket Loops by Gear4, I was at CTIA last spring. I was quite surprised that no one on the integration of an iPhone / iPod to a keyboard before had thought.
Pocket Loops could quite easily look as only two octaves of the piano keys are included, but it is actually quite complex to use.

The user can select the keys with 13 included synths play to produce loops, and then combine for a hit track. The beats were created, can be performed with a drum kit that House, Drum & Bass, Hip Hop, Reggae, Rock and many more covers.
The Pocket Loops comes with an app, which is now ready to use ready in your iDevice connector to download. Need iOS 4.2, but the app allows the user to email tracks to share with friends.
In addition to remix some tunes with drums, bass and melodies, the user can access to some cool effects like echo, chorus and the XY Filter Pad.
Okay, so if you can this thing, make the cool tunes, the next big music artist could already make the latest hit on it at this moment?
