Hmmm... Lots of interesting perspectives here. Personally i doubt whether CDs will 'disappear' - certainly not by next year. But they have now joined vinyl and cassette as 'old-tech', but like them, will continue to be produced for the forseeable future. All the formats, digital and hard-copy, can - and do - co-exist, with people using whatever suits or attracts them.
I agree with kopper that, as a long-time radio DJ, playing ALL vinyl on-air was a pain-in-the-arse and that CDs were a boon! We have been mp3-ing our new release CDs at the station for the past seven years or so, and have an on-going job of adding the older CDs to that collection, whilst still keeping our CD/vinyl/tape collection active (we have over 70,000 items from our 31 years of broadcasting, a very cool library to play from, I can assure you!), so, as DJs, we have the choice of using all, or just one, of the various formats (including using our personal iPods). On our shows, the Cat and I generally use CDs because of their 'easiness', with some vinyl (particularly rare local singles or albums) and very occasionally, something from the mp3 collection. We hardly ever use the iPod due to its inferior sound quality... though we do use music sourced from downloads in our "Obscured by..." show, this is because it's the only way we can get hold of some of these rarities to play, so we put up with the sound.
All these formats have their positives and their negatives and each person will use/buy whichever is most relevant to them... but I do agree that there is nothing quite like the feel/look/sound - and even smell - of vinyl products! [I am very proud of the vinyl that my music has been released on - though last year's single had a download card included - but as it was a 'limited release' of 200 (pic sleeve and bonus inserts etc), I am glad it still lives on available to buy as a download-only]
Yep... I'm still a vinyl junkie!!!
