Plethora of players

My mind boggles at the hundreds of competing player designs released, most with no unique
features to recommend them.  The only sense I can make of it is that they must be personal
projects of younger sons of Japanese and Taiwanese businessmen, and that breakeven is not
required.  If so, perhaps that identifies a route to getting Rockbox players produced.
Complete Japanese language support may be more important than has been realized.  Getting such
players marketed outside Japan or Taiwan would be another hurdle.
