THE LATEST CONSUMER REPORTS has a bunch of new digital camera reviews. As with the big-screen tvs, the most noticeable thing is the drastic decline in price. Canon sweeps, with the $149 SD1100 taking top marks in the “subcompact” category, the $400 Powershot G10 winning in “compact,” and the $320 SX10 is winning in the “superzoom” category. They didn’t test my Lumix LX3, though, and I think it would be hard to beat.
