Write Way Pro has been free for a year at least. I downloaded it for free a little over a year ago. I don't think you can call it "Abandonware" since the author seems to want to keep control of it, and still seems kinda proud of it.
I thought it was a fairly decent writing tool, not all that different from Scrivener, but I was concerned about becoming reliant on a product with no future. I think Scrivener and the equally free SmartEdit Writer (formerly Atomic Scribbler) are better tools and have more of a positive future.
