Well, maybe. But I doubt that non-re-writeable disc based devices could
read them (unless they're planning for it, but then, don't you reckon
they'd be touting re-writeability as an upcoming feature?)

Right, Dataplay is cute, but three things make it less than exciting:
1) Write once.
2) You have to *flip it over* for 500MB. It's really just 1.5x an MD,
per side.
3) SDMI! This is what really makes it fizzle for me. It's got the same
blasted Audio/Data firewall that hobbles MD so badly.
Much more interesting media for me are the two 50mm MO discs announced
for still camera use. A 1GB version from Sony/Sharp (see
http://www.sony.co.jp/en/SonyInfo/News/Press/200003/00-0323/) and a
730MB one that Sanyo/Olympus/Hitatchi/Maxell (see
http://photo.askey.net/news/9907/99072801newstorage.asp) have
announced. Without a firewall, they would make an *awesome* portable
music format! With a firewall? Well (yawn), we already have MD.
Does anyone know if there are any real (read: available) Dataplay
based devices yet?
