Maybe not so interesting, but just want to inform about my usage of my DX50 of the 13th batch running 1.2.8:   No issues at all so far. Have music both on internal memory and external formatted exFat. I don't use artists, albums etc although they are correctly tagged. Just using the file...

Received mine yesterday. No flaws so far. Quite impressed by this small wonder machine :)

Well, it's my first post here. Just ordered the DX50. Will be interesting to try it out.
