That's exactly my use case. Every single time I read (not totally as reading from a regular screen is not for me) a book from a PDF and I like it I definitely purchase a physical copy. I do the same if I hear an album that I like. Imagine like spending 150U$S on a book and it turns out that the approach is not for you. Every book is different and so are readers. What might be a good read for me might not necessary apply to other readers. Z-Lib and Libgenesis are a bliss and hope they are never taken down.
