I converted to ebooks from “tree” books about five years ago (with the exception of cookbooks, but that’s another blog post . . .)
Ebooks are awesome because you can buy or borrow them without even getting off the couch. You know the dreadful feeling associated with finishing a serial novel in the middle of the night? The feeling generated by the knowledge that you will have to wait until bookstores open the next morning to get the next installment? That feeling is gone! Woot! A few clicks and you have new reading material without leaving the house or putting on pants.
What about you? Ebooks or tree books?
