One of the most impressive DAWs on iOS just got support for the new Dropbox SDK, with integrated login. A handy feature for any app that has lots of stuff you'd want to get on to your computer, without the use of iTunes' file-sharing or jailbreaks!
I haven't had a chance to play with this. Have any of you? It seems pretty feature rich, beyond the simple recorder suggested by the name. The inclusion of virtual instruments and racks of effects makes this a full-on DAW.
