I've shot with plenty of pont and shoots over the years, never really saw live view as being good. Most of the time I turned off the screen and used the crummy, unaligned optical finders. On my P7000 I use the LCD, but I'd still rather use an optical finder. I guess I'm just too old fashion and set in my ways as an SLR shooter?
For street shooter I can understand the desire to be more discreet when taking photos of strangers/unwilling victims.
