Do you usually purchase digital or physical books? Why?

Ebooks have their convenience, and once in a while I'll take a free one if offered, or pick them up cheap in a bundle.

But physical books capture my interest way better. More satisfying to hold and look at. Having a physical object around is a reminder to read. And paper books are better for tuning out distractions. If I try to read ebooks on a phone, tablet, or PC I can easily lose focus (though nice dumb-device readers are surely out there, I don't have one).
