R837 pet shooter, HP also unveiled their Photosmart M537 and M437 point-and-shoot cams this morning. The M537 brings a 6 megapixel CCD, 3x optical zoom, 2.5-inch LCD and HP's steady photo anti-shake technology. The M437 drops the sensor to 5 megapixels and scales back the LCD to a wee 2-inches, otherwise it's the M537's feature equivalent. Both cameras can run off standard AA batteries if you want to make the little babies and Al Gore cry. Expected to hit the virgin hands of digicam noobs this April for $130 and $110 for the M537 and M437, respectively. Yeah, that's pretty cheap.
