Bad Widget (so far) - I also experieinced 100% CPU utilization (which will overheat your powerbook) when fetching local listings which takes several minutes, and still high cpu after that. I also had problems rotating the widget to enter my zip code. It eats up around 25-33% processor time even when running in the backround. A very sloppy widget (thus far) that I had to delete. I also had problems deleting the widget, im not sure if that was Apple's fault or the widget's fault.
