HP has issued a refresh to the Photosmart M line with the new M547. The upgrade purports to improve on the already solid M537, but we’re seeing more in the way of tradeoffs than enhancements. While the M547 does offer a slight bump in megapixels–from 6.0 to 6.2–and supports larger-capacity SDHC flash cards, buyers will have to compromise with a smaller 2.4-inch screen and some degradation in picture quality.
At 3.8 x 1.5 x 2.5 inches and 4.8 ounces without batteries (6.4 ounces with batteries), the M547 felt solid without weighing us down. The 2.4-inch QVGA screen was bright indoors but tended to wash out in very bright sunlight.
