Moving onto Kindle unlimited

I've never liked the idea of exclusive contracts. If it hadn't been for Amazon's insistence that my ebook cannot be available anywhere else, I'd have signed up to unlimited a long time ago. I have no problem with being paid per page read, it's cutting my books off from apple users and the like that i don't like. However, it looks like the time has come to go unlimited, Starting with Waterloo Sunset. If you are an unlimited subscriber, look out for it.
