I prefer regular books, 10 times out of 10. The information contained doesn't seem "real" if I can't hold something physical. The tactile touch, the texture of the paper etc. Essential things to me.
However, from the view of an amateur publisher, it's hard to top the comfort of making ebooks. I enjoy writing, are fond of doing illustrations and find pleasure in doing graphic design. But then it stops. When I'm done with it, I'm done with it, and want to find new goals. I dislike haggling over price with printers, find no fun at all in questions about distribution, feel ill at ease over most of the marketing aspects and just get annoyed over currency exchange rates, bank fees, national checks that can't be cashed etc.
Ebooks is like a dream in comparison. If a week is slow, and I have no rehersals, I can relax with things I enjoy, writing and drawing. And then, when done, just upload it and that's all. No boring things to bother with. And should there be any problems, too many computer support questions, the ebooks can all be taken down within seconds. Fast and simple.
Without ebooks, I would probably not have released anything at all in english during the last 7 years.
So it is a paradox for me. I prefer to make ebooks, but prefer to read normal books.
