The most common user issue I get is basically "too few widgets". Well, good widgets targeted for mobile devices will surely be more common after Tizen comes out. Meanwhile, there are quite many widgets available for Symbian WRT and Opera.
Opera widgets are mostly intended for desktop and often work poorly on mobile devices. But there are some good ones there. All of them are accessible through http://widgets.opera.com/. Just go to that address with your N9 and try them out.
Symbian widgets are a bit harder to get (albeit more suitable for mobile devices) because you can't just download them from the Nokia Store. Some of them, like the AccuWeather, are also available through the author's website if you know what to look for. There is also a good collection of 50 small games available at http://www.drjukka.com/50Widgets.html (though these are designed for devices with traditional keypad).
Let me know if there is a good place out there filled with good widgets!
