iRiver makes solid state MP3 players,
like an Apple iPod, but record sound
without adapters and peripherals.
(I told Apple I wanted to do recording,
but did they listen to me? No.)
The iRiver iFP 7xx and 8xx models take external
mics in their "Line In" jack. Don't use the
T10 and T30 series, they only use a built-in
mic, only good enough for voice notes.
