If you use a digital camera (I use a Canon EOS Digital Rebel/300D myself) and that camera is an SLR, then it most likely can record images in RAW format. In general, you should record your images at the highest resolution possible. If you only have a small memory card and are worried that you can only record a few RAW images on it, then it's time to buy a bigger card!
So does everyone have an ultra-slim camera announced yet? I thought we were about there, but here comes Casio with the EX-S500 - a slick looking model that is .54 inches thick at its thinnest point. The 5 megapixel, 3x optical EX-S500 comes in orange, gray, or white and features a 2.2 inch LCD. The battery is good for 200 shots and the EXILIM engine includes Anti Shake features to minimize image blur. The camera can also shoot MPEG-4 movies at 640x480 resolution and 30 frames per second (fps). The internal memory (all 8.3MB of it) can expanded with SD/MMC memory cards.
The Canon Powershot S70 represents an overall excellent camera that makes a few compromises. It's strength lie in the overall flexibility of the camera and its ability to compete even with bargain dSLR cameras while remaining fairly compact. The S70's main weakness is the low light and nighttime performance especially for medium distance group photos or portrait shots and may require use of external flash or lighting units (although you can compensate a bit with a tripod and optimizing the settings in manual mode).
Sony has announced the Cyber-shot DSC-W5, a 5.1 megapixel update for the DSC-W1. The W5 also features a large 2.5" LCD screen, 32MB of integrated memory and 3x opitcal zoom. The DSC-W5 will retail for $350.
Canon has announced the new PowerShot A520, which is an update of the popular A85 and a 4 megapixel version of the recently announced PowerShot A510 (3 MP). The PowerShot A520 features a 1.8" LCD, SD memory card slot and runs on two AA batteries. The A520 should be available in March at an MSRP of $299.
