With Rio finally out of the picture (RIP buddy) Sony may actually have a fighting chance to get some sells in the primarily Apple only MP3 player market. This is Sony's fourth adventure into HDD based MP3 players, and it is actually a decent player. This is a 20GB model and has roughly the dimensions of a thick credit card. This looks good, sounds good and has a great battery life (30 to 40 hours) to boot. Although the price tag at 199 (around $350 USD), the lack of line-in recording, voice recording, and color screen as well as the crappy Sony software are all setbacks.
