iphone music apps

Can anyone recommend any music making apps for the iphone? There seems a few out there (4 Track, Beatmaker, Flourish, Xewton Muisc Studio, etc).

Ive got Argon which is a virtual analog synthesizer/sequencer. I havent been able to suss out how to use it properly yet.

I know alot of folk on here would rather sit on broken glass than own an iphone. Thats their choice but I think theyre great.

I've nothing against the iPhone, but you'd be a lot better off making music on a computer (PC or Mac), there'e plenty of free or shareware music programs about, the old addage of decorating through the letter box springs to mind. Unless there is some way of hooking up an audio interface, usb keyboard and decent size monitor i can't see the point.

My 15 yr old son says Beatmaker is cool.
