I had the predecessor, the MP850 / 4GB and was very enthusiastic. In July I have eye plays the last software update. Mature! The MP860 / 8GB is slightly larger, has a better and larger display. The battery life is OK for me. The sound is great, and I must say that I run my MP3 player with a "big" headphones. However, I have the impression that some Presets do not work quite right (??). The menu structure is slightly different than the MP850, which is quite advantageous. I very often use the built-in FM radio. That was the MP850 somehow better than the MP860 (drum also only 4 stars): When you turn on a stored transmitter, the device is something - the desire stations but only after operating the> button. I have already written to Transcend (no answer) ... Occasionally I look at Transcend to the download page, if there is a firmware update available. Not until now. So up to the two issues raised can not be faulted on the device and I enjoy it.
Addendum 19.08.2009: There are now a firmware update. Equalizer is now OK, but the radio has the little "quirk" yet.
