In fact, it's starting to appear in advertisments. One device claims it can do Ogg Vorbis at Q10!

I'm partial to MiniDisc myself, but that's mostly because I've never really bought into putting my music on the computer. The new HiMD devices can function very much like an iPod-class device, especially as the new HiMD disc is 1Gb in size and ATRAC3plus is very likely as good or better than AAC. (I haven't been able to convince the fiancee that AU$500 is worth spending on one...)
