The strong parts are that it's very easy to use, makes grocery lists, and things like that. It's also very popular, so there are many recipes and lots of whole cookbooks available online for free to add into it. There is also a way to copy recipes directly from Internet Explorer to the program, but I don't use it because there is no plugin for Chrome.
For weak points, there direct support isn't that great and there seems to be some issues with newer versions running on Windows 7 and Vista. I use version 9 and had to change where it was installed because Windows user account control wasn't wanting to let me make changes. There are forums and a Yahoo group for users that can be pretty helpful for problem solving and for finding cookbooks and recipes, but the official support is lacking. I also had trouble figuring out how to send recipes by email.
