Crystal Reports is another not-blogged-about application. I suppose reports aren't leading edge like, say, XML. I've been using it since v2 I think, and now it's on v11.
Despite being great for paper layout, it's pretty poor at Excel output, which is where we need to use it. The trouble is it's stuck in a paper page metaphor, which doesn't work when you want to put reports out into a grid like Excel. They've tweaked the export capababilities over the various versions, but haven't overcome the shortcomings of the page metaphor.
