I only use my old vinyls now, since I've only bought CD's for the last few years.
CD's are just so much more flexible and easier to work with than vinyl - and thats not something which I would have said even 4 years ago. For example, being able to lengthen a CD track which the audience are enjoying, or shorten a CD song, which has halved the dancefloor, without the audience noticing.
This(?) months ATB magazine (mainly urban music from what I could gather during the 10 minutes browse I had in WHsmiths

) had a CD Vs Vinyl debate transcripted up, and those questioned gave vinyl little more than 5 more years.
