I was thinking about this earlier. At present my experience of mobile music making is restricted to a limited number of devices or device types. Let me explain:
Device I own / or have owned:
- Various Palm OS devices
- Various PocketPC / Windows Mobile devices
- MadPlayer (weird device that generate music via algorithm)
- Laptops in general
Devices I am aware of / would like to own:
- Nintendo DS
Of course, what is left is the stuff I don't know about, and of course that I can't comment on.
I did have a little sniff around for any interesting apps running on Symbian, but I could find almost nothing.
I'd be really interested to know of other platforms or devices that are useful for mobile music making.
