To be honest I'm the same way now, especially since I can keep my entire collection of music copied over to my computer in one space. I still like buying physical copies of my favorite metal bands as collectibles, though.
And yeah you can get the digital collection for much cheaper. I think CD's are $8.30 with shipping if you buy one at once, which means $1 to Kunaki, $4.30 to shipping and $3 to me. The entire digital collection can be obtained for even less
The only thing I hate about digital is if the service deletes your account or files after a long period of inactivity like iTunes did with my purchases. Same if the service shuts down permanently. Good thing I had backups of Bass Launch's and Instant Remedy's music.
