The W55 is more than three years old, so we strongly recommend that you buy a newer model with better specs for less money. Check out the W370. Here's what we had to say about the W55 when it was released in January 2007:
Whether clad in precious pink or stunning silver, the Sony Cybershot W55 is a people-pleasing ultracompact. These 7-megapixel cameras are more than enough for the everyday user, and the lithium-ion battery is good for around 400 photos before it needs a refreshing charge. The W55 is also available in light blue and black colors, and a version with a smaller LCD, the W35, is available in silver only.
