I would buy the CDs in a heart beat, I just bought a box of 100 from someone.
Why? Because I rip them all to my music server in FLAC and kick back on my sofa browse and play music.
I stream but just when making dinner, something like that. I don't feel that streaming is all that and I am just old school I prefer to have my music on a physical medium that I can pickup and touch. And I don't feel that streaming HD has surpassed the quality of CD by a significant margin.
But thats just me.
