We have been testing the iPhone for two weeks, in multiple usage scenarios, in cities across the country. Our verdict is that, despite some flaws and feature omissions, the iPhone is, on balance, a beautiful and breakthrough handheld computer. Its software, especially, sets a new bar for the smart-phone industry, and its clever finger-touch interface, which dispenses with a stylus and most buttons, works well, though it sometimes adds steps to common functions.
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.
But the iPhone has a major drawback: the cellphone network it uses. It only works with AT&T (formerly Cingular), won't come in models that use Verizon or Sprint and can't use the digital cards (called SIM cards) that would allow it to run on T-Mobile's network.
what is he talking about no T-Mobile use??!?!?!
