So, fun story. Scrivener was, once up on a time not so very long ago, Mac-only. I got a MacBook at the end of 2009. The first thing I installed was Firefox. The second was Scrivener. XD That was back in 1.0 when Scrivener was rather feature-light compared to now, and so for a while I went on using Liquid Story Binder in a Windows VM, but then Scrivener 2.0 happened and I happily settled into it. (Though sometimes I do miss some of the features of LSB, I've evolved my writing process to work around it.)
