Please compare and contrast the Sony Cyber-shot DSC-HX5V/B and the Sony Cyber-shot® DSC-H55. Aside from the differences in price, availability, and megapixels, is one camera better than the other? They do seem to share several similarities. Can those of you who have used either one or both share some inside information with those of us trying to decide on a new camera? I own and have used the DSC-H3 and the DSC-H10. Which of the two new cameras is more like the H3 and the H10? Please let me know. Thanks!
