When do you choose vinyl over digital?

For those who play (and buy) both vinyl records and CDs (or digital downloads or CDs ripped to a server), here's my question:
When contemplating a new purchase, something that is available on vinyl and on CD, how do you decide which to get? For me, the choice is sometimes easy -- when, say, a longtime favorite artist comes out with a new album, I'll most likely get the vinyl, adding to my collection. Others, whose work I've mostly got on CD (or don't have much of in any format) might lend themselves to picking up the shiny disc. But sometimes I can't decide.
One example: I've heard (and enjoyed) some Vampire Weekend and felt like giving them a listen. I can pick up their three CDs for a bit less than $30, or could get the trio of vinyl recordings for not quite twice that amount. I haven't pulled the trigger because I'm not sure which way to go.
When in similar straits, which way do you lean -- and why?
Thanks.
