Cameras with longer battery life can take more photos before exhausting their batteries.
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
Cameras with more dynamic range allow you to take photos with dramatic differences in highlight and shadow areas while retaining detail in both.
Think of a brilliant sunset on a rocky beach: Bright sunset in the background, with dark rocks in the foreground. High dynamic range means more of the extremes will be faithfully reproduced.

Sleek, more professional camera design; faster autofocus system and burst modes; solid performance at high ISOs despite the bump up in megapixels.
Significantly more expensive than previous model; slow buffer clearing with RAW images; with kit lens attached, camera becomes less portable.
