| The Bottom Line | The S66 packs a wealth of multimedia and communications features into a typically slick-looking Siemens package. | The Sony Ericsson W760i is the best Sony Ericsson Walkman phone we've seen, by far. It corrects one of Sony Ericsson's usual design pitfalls while offering a generous feature set and satisfying performance. We can suggest a few tweaks that should make it a winner. | The Siemens SX66 is a decent smart phone for users who like the form factor and need world-roaming capabilities, but we were less than pleased with Cingular's service. | ||
