The C905a's Entertainment app handles music and video playback as well as photo viewing, and it includes a handful of games. The interface is reminiscent of what you see on the PlayStation Portable or the PlayStation 3 game console, and it works about as I would have expected; if you've used an MP3 player, you probably already know how to use the C905a's media player. The player is easy to navigate, and it's the most attractive part of the phone's interface. It won't replace your existing MP3 player, however--the C905a lacks a standard 3.5mm headphone jack.

The C905a's headlining feature is its camera--and it's the best cell phone camera I've ever used. Modeled after Sony's Cyber-shot stand-alone camera line, the camera here, with its 8.1-megapixel lens, rivals basic point-and-shoot cameras. Photos come out pretty sharp, though colors aren't quite as vivid as with a dedicated digital camera. The camera features a Xenon flash, which performs reasonably well indoors. It also offers a handful of advanced functions, such as red-eye correction, digital zoom, image stabilization, autofocus, and a macro mode. I was particularly impressed by the macro mode, which took crisp, sharp photos. To add to the camera-with-a-phone nature of the C905a, the handset has a dedicated shutter button, a photo-preview button, and a button to toggle between the still-photo and video modes, just like most point-and-shoot cameras.

If you're the type who takes a camera with you everywhere and you don't want to carry around too many devices, you may want to give the Sony Ericsson C905a a closer look. If you want a more advanced phone, however, consider the Nokia N97, a smartphone with a high-quality camera.
