content: I have had the TxFm 512 for almost 2 weeks now. It's a breeze to add/delete songs to the unit using "drag and drop". Both W2K and WXP recognized the unit w/o any problem.I have problem plugging the unit directly into my machines' USB ports due to the ports location and orientation, but an USB extention cable solves the problem.The conversion software is very useful because I can store more MP3 songs in 64bit format ... my original files are either in 192bit or 128bit formats. I don't think anyone can tell the difference from listening thru earbuds.Pros :1) can display in different languages2) available random songs (in folder) and random folder function3) conversion software is user friendly4) small and lightCons :1) should sell the 1G version in US (it's available in Taiwan)2) should provide neck strap (came w/ armband and beltclip only)3) volume output is too low if used thru FM modulator, using earbuds is fine though
