I used to go on CD sprees to get stuff that I normally couldn't hear or find via the normal means. I have a lot of Canadian stuff on CD (Max Webster, April Wine, Kim Michell) due to the fact that you don't hear it often on the radio. However, I've found that Pandora helps a lot when you have a less-than-mainline musical craving.
Here's the way I see it--listening to a CD or an MP3 is like having a beer. Having a normal beer really isn't an experience--you've had one, you've probably had many in the past, and you'll have many in the future. Vinyl forces you to stop and take the time to appreciate it, like having a brandy or a cognac, or something that forces you to drink from a snifter. While I own all of Rory Gallgher's albums on vinyl, I also own them all on CD and have put them onto my computer, mainly for the convenience. Getting all of the albums on CD wasn't too hard--where I bought music as a kid, you could get 10-20% off anything if you paid in cash, even on ordered stuff. Getting all of the albums on vinyl was a loose work in progress, which happened whenever I'd visit a big town that had a record or an import store. However, all of my Les Paul, Barney Kessel and Django Reinhardt albums I refuse to put into any form of electromagnetic format. To me, guitar jazz is that one thing that you can listen to when you're sitting in your basement or den, you have a good mixed drink, and you have a good book, making a deliberate attempt to wind down and relax. The Rory albums, as well as the other various ones I have I like to put on when I'm putzing around in the basement with other stuff.
At the same time, I personally find vinyl fun--the one year I was a student DJ on the campus radio station in college, 95% of the stuff I played was on vinyl, and sadly, I was the only one for most of that year who knew how to work the turntables. One song was almost a routine--put on "I'm Going Home" by Ten Years After live from Woodstock, dash outside, and move my car because I was only allowed to park in the lot closest to the station til 8, when the campus clinic opened up, and the parking was for clinic patients only. I'd park in the general use lot on the other side of the building, get through all of the doors and get back in time to crank Alvin Lee's solo on the studio speakers.
