I'm a musician. Right now I use my laptop for recording, but taking a laptop everywhere isn't always possible - let alone mics and music gear. Now that the 2G Touch has line in, mics can be hooked up to it (even if they are just Apple ones). What kind of quality can this give? Good enough for recording ideas and very rough demos? Field recording? Or, is it more like phone quality sounds? I'd appreciate any input on this!
