Casual shooters who aren't terribly picky about relative sharpness of the background and the foreground will be very happy with the A33 and A55's continuous-shooting performance. For instance, at this small size, everything looks in focus, and the moment's been captured. But at full size, you can easily spot that the AF system locked on the Coke ad rather than the bull and rider. This is partly due to the relatively difficulty of keeping the subject under the AF points with an EVF, which blacks out briefly after each shot as you burst. Optical viewfinders black out as well, but it's still faster or easier to mentally compensate for than with an EVF.
