Did'nt answer the question. Have you used it DE? Do you have any supported hardware (windows mobile phone or others). If you haven't then you can't make a valid comment on it.
The DE player's probably outsold OS 3.9 and 4. We also already know (from Hyperion) that Amiga Inc had them port OS 4 to some phones/PDa's. This plus something DE like might attract new users. At least Apple had sense and went for users with deep pockets. Commodore went low end (... for quick $$) now we're stuck with users that just complain.
I know what has happened here you have read things that Amiga Inc announced, that never transpired, and believed it as truth.
Way way way back in time OS4 was supposed to have a DE player. Did it happen ?
