Walt Mossberg has published the first hands-on review of the upcoming Apple iPhone. After two weeks of testing, Mossberg claims, "the iPhone is, on balance, a beautiful and breakthrough handheld computer."

On the topic of the keyboard, Mossberg writes,"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."

Mossberg concludes saying, "despite its network limitations, the iPhone is a whole new experience and a pleasure to use." Read the entire iPhone review.
