DX may be able to do the widget part of it better, but I don't think it can learn your interests after a while, and so display what's most relevent to you. The news widget learns the type of articles that you click on the most, and, after a while, it can display what your interested in the most. For example, if you always choose sport-related headlines, but never technology-related ones, you'll get more news on sport, and less about technology. Also, the RSS and atom feed reader can automatically add feeds - dubbed "Web Clips" from sites that you often visit.
Of course, if someone does churn out a DX widget that does all of that, I'll shutup.
