  1. Not a bad idea, but I find there's nothing wrong with the iPhone's built-in mic for my purposes. There's also plenty of cheap portable recorders out there. My biggest problem with these products that dock your iPhone/ iPad is that they seem to forget we often have protective covers on them we don't want to fiddle with.
