Aiwa has a portable solid-state MP3 recorder that will record in MP3 format at 44.1khz stereo (see http://www.aiwa.co.jp/english/exhibi/new_p2000/mm-fx500.html). It offers 10 hour playback and 3.5 hour recording times. This seems roughly on par with MD playback/recording ratios. My understanding is that MP3 compression is on the same order of complexity as ATRAC.
