Trying to convince myself that I need a compact, based on the idea of wanting always to have a camera with me. Some user reviews, e.g Amazon, claim the LX5 is not as sharp as the LX3. What do you think? One thing I'm not sure about is the lack of a viewfinder. I was looking at the Panasonic based on bang-for-the-buck, but would consider anything similar - if the picture quality is up there, and good low-light performance (something users also slate the LX5 for over the LX3).
