This is the 1020 model ... I got the 1021 model from Target a few months ago. The difference appears to be a circular jog wheel on this model for menu access as opposed to my unit with its horizontal buttons. I loaded no software at ALL for my player, just a firmware updater. Its simple drag n drop operation, copy the files from your PC onto the player via Windows Explorer. I don't bother with WMA and use many high bitrate mp3s, finding 160 to be the minimum for my ears. The headphones are good units but since they are quite sizeable require an ear clip that may bother you after an hour or so of usage. I leave one side off (to answer my cell) and alternate every 30 minutes to the other ear. The original Lyra players had that awful copy scheme, as an earlier poster mentioned, but this unit seems to be just fine. Run time from 1 AAA battery is probably in the neighborhood of 5-7 hours (depending on brand used). Add a big SD card and you are set. There is no noticeable lag on the player from onboardsongs to the SD card ... totally seamless transition. Good unit for the price.
