| HTC Touch Diamond | 3 The Touch Diamond's display is lively but the TouchFlo interface isn't intuitive. Also the interface was sluggish and I've never been a Windows Mobile fan. | 3 The Touch Diamond's 3D TouchFlo interface is cool, to be sure, and it goes a long way in making the Windows Mobile user interface more consumer-friendly. However, there's a learning curve, and you still have to deal with some extra steps for simple tasks. Plus, the slow performance doesn't make for smooth navigation. | 3 While the iPhone excels with its touch interface, the Touch Diamond fails. The interface is certainly a lot easier to use than other Windows Mobile phones, but texting is a near nightmare with the tiny keyboard, and there's a steep learning curve in getting used to the sensitivity of the touch controls. | 9 |
| Apple iPhone - 8GB | 5 The best thing about the iPhone is that you can pick it up and immediately know how to use it. Also, while the touch screen lacks tactile feedback it's quite responsive. | 4 One of the great things about the iPhone is its ease of use. With a beautiful, responsive touch screen and intuitive interface, you can pretty much use the phone straight out of the box and you can't ask for much more than that. Though I prefer a tactile QWERTY keyboard, the iPhone's onscreen keyboard wasn't bad. | 4 Perhaps because of its capacitive touch-screen display, the iPhone simply has the touch screen to beat. The zooming controls are top notch, and you don't need to rely on a stylus for detailed controls. Texting is easier with the horizontal keyboard option. | 13 |
