Well, I'm not sure about everyone else, but my iTunes AAC files, DRM stripped by Hymn (before an ITunes upgrade awhile ago) now play perfectly on my H140!!!
As soon as a week ago, they were not playing. Before it would skip as the processor couldn't keep up, and then a week ago it would choke on the metadata - but now it works perfectly! I'm guessing the final straw was the metadata fix in the daily build of Oct 12th by Magnus.
This has been the feature I have waited forever for and I love it! Now I can share files with my girlfriend who has an iPod.
Thanks to everyone for all the work so far - not just for this, but also in making Rockbox everything that it is. My H140's original firmware was horrific, and with Rockbox - it's everything I could ask for. Well done.
