I'm considering buying an iPod Touch (4th generation 32GB model) but just learnt that it no longer has analog audio input capabilities like earlier iPod Touch models had. Audio recording apps such as FIRe are said not to work with the 4G (I'm not sure if this means it won't work at all, won't work with an external mic which it needs, or will just work with the built-in mic which the app doesn't recommend), so I'm wondering if this applies to all audio recording applications or just the ones which demand the use of an external mic? Given that it has a built-in mic I would assume you can still record audio (in mono?) although not in Hi-Fi quality (hopefully "good enough" for legibility though) I understand from the above link that USB mics are supported but aren't yet available. I would like to have the ability to record lectures, conversations etc. I bet I could still get a 3G iPod Touch (probably cheaper than the 4G), but the higher resolution, video-phone capabilities, camera (although it's crap from what I read, but still a camera if you don't have anything else at hand), faster processor etc. are appealing. Anything else missing from the 4G which would make a 3G a better choice?
