JetAudio is at it again, with a new media player dubbed the iAudio 5. Similar in size to the iAudio U2 (which is to say, real small) the 5-series comes in capacities up to 1GB and seems altogether similar to the U2. The only major exceptions seem to be that it requires one AAA battery (as opposed to the U2's internal Lithium-polymer) and it supports a slightly wider range of audio formats, including Ogg Vorbis. Probably not a bad piece for the price ($129 - $199) if their previous models are any indication.
