I'm not sure, Marbles, to be honest. I remember that in '88 I had maybe 40 CDs, and there was only one other guy in my residence hall at the U that had a player. And people were stunned at my *huge* collection!

I don't really remember how long it took til pretty much everything I wanted was out on CD (actually, it still isn't).
I wonder how well CD would take off if it was launched today and had to compete against DVD-Video, Broadband internet, MP3, X-Box, PS-2, Gamecube & PC gaming? Even giving the crushing sonic superiority of DVD-A & SACD, I just don't think it's realistic to expect any audio-only format to acheive the kind of success that the CD did. In part I don't think music plays the same role in most peoples live that it used to, and the masses don't listen in the same way. Hell, even the CD seems to be on the ropes, if you can believe the major labels! So any expectations should probably be revised downward.
Right now by my estimates there are over 2,500 titles available, with a tremendous variety especially of Classical (which is near & dear to my heart). How many "should" there be? Beats me. Do I wish there was more? Definately. But it sounds so much better (to my ears) that I'm gonna stay the course. I don't have a crystal ball to know if it will succeed, but I'm optimistic.
And RussKon, that's kinda a straw man arguement, isn't it? I might have misread ID's post, but I didn't see him say anywhere that those two recordings sounded "like ass," only that most of the ones he's heard did. You probably needn't accuse him of having his head up his arse on those grounds...
