I don't see the appeal of hardware-induced quality loss (vinyl) over software-induced quality loss (compression). At least in the latter case, quality loss is specifically designed not to be perceptible.
I agree with >>20 about hard drive based music players. All my MP3/Ogg/MPCs together don't even approach 20 GB. Storage is effectively infinite. Additionally, I arrange my playlists in order of mood, not artist; I don't want to bother with swapping CDs or <insert contemporary physical medium> every other song.
