this is a great piece of equipment. it does all you want it too and more. the sound quality is amazing, with many different EQ settings. all the videos i have played look great too, and the firmware updates actually improve the things you can do. eg the first update i received was one that allowed file transfer via bluetooth and other things, whilst the last one i did allowed me to play some games. the datacast feature is good too, when i dont have time to look at the news o something, i just look on this little thing, and it tells me all the main headlines (after its connected to the pc). the touchscreen actually works! although my bro's find it a bit tricky cos it takes a little getting used too.
saying all these positives, there is one negative...the lack of formats you can play. this is pretty irritating when you want to get a video from a mobile phone via bluetooth. i end up having to take it home, and convert it with the supplied samsung software. since it converts it to "svi" which is samsungs own special video format, the videos you do send to others often cannot be played.
however this in my opinion is only a small problem, and can be overcome without too much inconvieniance.
overall a great mp3 player.
