I've worked with audio in a radio station, and at least in our case, we have the DAT deck just to collect dust, ever since CDs are burnable and cheap. DAT is dead. It was very common to see it in audio editing in universities in the 90s down here, though, expensive as it was.
Yeah, I remember in the late 90's my local non-HMV music shop were still selling a few pre-recorded MiniDiscs on a crappy tiny little stand. Then they started selling SACDs last year, but I guess it didn't work out too well as they have none now. Yeah, I kinda forgot how expensive big Flash RAM is. And MD players were quite popular here too. It's only really the last year or so the HDD players have got more popular - especially with the iPod which was one of the big things this christmas, it seemed. Even Sony are making HDD players now! On the subject of Atrac though - I have an Atrac/MP3 CD Walkman, and I must say that Atrac3Plus sounds like complete ass! I tried converting some CDs to 64kb/s Atrac3Plus, and was appalled by the quality. It sounds all warbly and laking any sort of fidelity - I've heard better sounding tapes! Anyone who thinks they can get any sort of decent quality audio out of anything lower than 128kb/s (that means you too, Microsoft!) are lying to themselves...
The idea of releasing selling music by the album on pre-printed media is antiquated anyway. The Japanese got it right, buy it by the track, record it on your own MDs. Only buy what you want.
Hell, the GS cube! ''16x time the power of the ps2!'' what happened to this project? they said Lucas would use it to create the special effects of the next star wars (wich was episode 2 at the time). that would be really cool to see a proto of this. Returning to the Pre-PSP proto, i personally still think the snes cd is more legendary. :smt045
