The Apple phone combines intelligent voice calling, and a full-blown iPod, with a beautiful new interface for music and video playback. It offers the best Web browser we have seen on a smart phone, and robust email software. And it synchronizes easily and well with both Windows and Macintosh computers using Apple’s iTunes software.

It has the largest and highest-resolution screen of any smart phone we’ve seen, and the most internal memory by far. Yet it is one of the thinnest smart phones available and offers impressive battery life, better than its key competitors claim.

It feels solid and comfortable in the hand and the way it displays photos, videos and Web pages on its gorgeous screen makes other smart phones look primitive.

The iPhone’s most controversial feature, the omission of a physical keyboard in favor of a virtual keyboard on the screen, turned out in our tests to be a nonissue, despite our deep initial skepticism. After five days of use, Walt — who did most of the testing for this review — was able to type on it as quickly and accurately as he could on the Palm Treo he has used for years. This was partly because of smart software that corrects typing errors on the fly.
