I still buy CDs when I go away, or if I've downloaded a bunch of stuff from a band and particularly enjoyed it, I'll buy their CD.
If Amazon would sell me albums on MP3 I'd happily pay for music, though. I won't buy regular DVDs now, though. I can get as-good-as or better than regular DVD quality films at EC$15 (~US$5.50) from my local bootleg guy. No special features? Who fuckin' cares?
The only thing I'll consistently shell out the full money for is Blu-rays.
