It was the natural tool to use for me: I've produced thousands and thousands of PP slides over the years and, because I'm obsessive about how the diagrams in them looked ("because you don't want to put across the wrong message by mistake" - that's been my excuse), I was asked to jazz-up others' slides. Hence I've spent a lot of time with the application and have become used to it over many years.
As with all tools, knowing what it can do is half the job. Most drawing tools can produce excellent output if you know what you're doing and what they can do.
As to coast lines: don't just think of a handful of edit points and a few clever Bezier settings: add as many edit points as you need. And remember, I'm a bit obsessive with this, so there are lots of edit points on some of my maps. (Odlly enough, near me there is a place called Round Island, but it isn't that round; but in any case, I always start with the Curves tool, not a regualr shape.)
