Well, I've been using the free trial for a few days now and if you are already familiar with the old Apple News, the "News+" name seems pretty accurate. Basically, you just get a little more of the same kind of thing. At first I thought the Wall Street Journal looked very good. But after reading for a few days, you realize that quite a bit of what you see are stories you've already read. Each day there are only a handful of new stories. When you first subscribe there appears to be more, until you look at the dates on the stories. The trick of tapping on the sections at the top of the page just shows you the same stories. For example, if you tap on the "Opinion" link, you will see whatever editorials they have featured for the past few days and not all the editorials in the current edition.
This is all fine, but if anyone thought this would be a cheap way to get the WSJ, they will be disappointed. And the same seems to be generally true for all the other News+ content. What you get is just a little bigger selection of stories than the free version of news. Will continue with this for the rest of the free trial, but not sure there's enough additional content to justify the $10 monthly cost.
