Generally, some of the advantages of the Canon SD880 IS compared to super zoom competitors include: it is slightly smaller (compact (94×57×24 mm) vs standard size (106×76×74 mm)), has better image stabilization (lens vs sensor shift), is thinner (0.9" vs 2.9"), is slightly lighter (195 g vs 413 g) and has a faster max shutter speed (1/1600 of a second vs 1/850 of a second).
However, on average it has a slightly narrower wide angle lens (28 mm vs 24 mm), has a significantly lower resolution screen (230k dots vs 1,040k dots), slightly lower maximum light sensitivity (1,600 ISO vs 12,800 ISO), doesn't have a touch screen and doesn't have a screen which flips out.
