Until recently, I haven't had an ereader and I've used readers for the computer to check all my formatting. The nook we have now is actually my wife's ereader.
The fact of the matter is that it's a luxury we can't afford. I am the sole provider for our family and we're barely making it. At some point, I'll be getting every ereader out there. Until then I'm doing the best with what I have.
Aside from that, I do try to participate in discussions, though I don't do so as much as I should. And I have been an avid reader throughout my life, primarily of fantasy, the genre in which I write.
