Color depth refers to the number of unique colors that a sensor can faithfully capture. Cameras with better color depth will demonstrate smoother transitions from one color to the next, and avoid "banding" in areas with subtle shading. (Blue skies are an example of where you might see color banding.)
More color depth is generally better, but you'll struggle to notice a difference between two cameras with less than 1 bit of difference. Color depth above 22 bits is considered excellent.

Cameras with higher effective ISO will be better choices for indoor photography, night shooting, and indoor sports photography, especially if you intend to make large prints.

Special note: The measurement standard for battery life stipulates that if a camera has an internal flash, it must be used for 50% of photos taken. For this reason, comparisons of one camera with an internal flash to another without will not be comparable
High quality images with lots of detail; Excellent graphical user interface is fun to use; Smart implementation of WiFi makes it relatively easy to share photos wirelessly.
Designed so much like a DSLR you may wonder why you shouldn't get a DSLR instead; Some performance issues, particularly slow buffer clearing and shot-to-shot speed; Initial WiFi set-up can be confusing.
AF speed vastly improved; Increased continuous frames per second (JPEGs at 12.5fps vs 10fps in G15); Solid build and ergonomic, comfortable feel; Excellent f/1.8-2.8 5x optical zoom lens; Advanced photographic features, including PASM dial and RAW capture; Dedicated ISO button; Customizable buttons; Excellent macro mode; 1080p/60fps Full HD video.
LCD screen not articulated; Larger design makes it not very pocketable; Optical viewfinder not very accurate; RAW burst shooting still slow; Wi-Fi is clunky to set-up & no remote shooting capabilities; No built-in GPS.
