In some cases, it's inconvenient. It's inconvenient to update. It's inconvenient to run the patches, etc. In other cases, people just don't see the need. They say, “It's working for me. It's good enough” or “I'm afraid I'll break it.” That's kind of an unfortunate legacy of our industry.
Right now, in some cases, it's the product itself. It's not updating itself frequently enough. When you buy into, let's say, a smart phone, you're buying into an ecosystem, so if it is the vendor who updates it, it could be a really cheap device that doesn't come with good support. Things like that all kind of factor into things. Sometimes it's manual, so some of the systems actually take a lot of manual effort to update versus some of the easier ones, for which, frankly, a little red bubble appears, and you just hit “Install” and you're good to go. It's kind of all of those factors. Sometimes we make it really hard in the industry.
