Over the past couple of years, Sony Ericsson has been something of an enigma in the cell phone world. Not only has it introduced far fewer phones into the U.S market than many of its rivals, but it doesn't let the absence of a carrier sway it from rolling out new models. More important, the company has shunned the industry's major trend--skinny phones--in favor of high-featured, well-performing models. Both the Sony Ericsson W800i and W600i fit this bill, and the company now introduces America to its third Walkman phone, the W810i. Encased in an eye-catching black, the W810i offers all its predecessors' high-end, powerful features, such as a high-resolution camera, Bluetooth, and a media player, while making a number of design changes. Overall, it's a quality phone despite some minor performance issues, but it's not a huge upgrade over the W800i. No carrier has selected the Sony Ericsson W810i yet, so it will run you close to $600.
