Pros Great RSS is almost a fee add-on
Cons None that haven't or aren't being addressed
Summary I don't understand reviewing Onfolio as just an RSS tool. It's simply one of the many tasks that Onfolio is designed to address. Comparing the product to a stand alone RSS reader is like comparing a Swiss Army knife to a paring knife. To quote from the Onfolio documentation "Onfolio is a PC application that helps you collect, organize, and share information you find on the Internet, receive in a feed, or capture from your system or network. Web pages, websites, multipage articles, images, a wide variety of file types, news feeds, search feeds, snippets of files or web pages—you can put any of these into an Onfolio collection. Then you share your research through documents, presentations, emails, websites, and reports. "
As for cost, it's a pleasure to pay for a software license when the product does what it claims to do, has very few bugs, and these are addressed promptly and couteously by some of the best tech support around.
Overall, one of the most useful and most used products on my systems.
