I still buy cd's - in fact it's not that long since i stopped buying vinyl and then only because i wasn't getting the time to listen properly and maintain the record deck.
Nowadays i treat downloads like i used to treat tapes - a medium for on the move or for running the ear over something i've not heard before, and i use itunes for convenience at home when i want to set up a playlist for something like when we have a few mates over. If i like it and it's available i'll buy the physical cd. I buy most used from ebay - nifty use of the right criteria nets me a lot of stuff for peanuts and now i've a new player and amp courtesy of this very forum the Thompson household is often bouncing!
A good friend used to own a real "Hi-Fidelity" type used record shop (Normans Place in Hull if anyone knew it) and i used to spend hours swapping rare vinyl, shooting the breeze, drinking coffee and taking the mick out of the customers in there when it was my day off ans swmbo was at work, great days and i miss that place terribly even now!
