Design and build quality

Apple iPhone 3G
The iPhone 3G has a larger surface area compared to the HTC Touch Pro and Samsung Omnia, but is the slimmest among them. Despite its size, the iPhone 3G is heavier than it looks. The rear feels plasticky though the overall build is fairly sturdy. According to the manufacturer, there is a scratch-resistant glass on top of the display that can handle aggressive usage, even with a stylus.

HTC Touch Pro
The HTC Touch Pro is the chunkier version of its Touch Diamond sibling and the reason, HTC included a QWERTY keyboard that slides from the left. This makes for the easy text entry. Needless to say, the Touch Pro is the heaviest of the lot at 165g, but the build quality is very solid. Flip it over and the rear reveals a familiar diamond-like exterior but in a non-reflective rubber material.

Samsung Omnia SGH-i900
In terms of size and weight, the Samsung Omnia SGH-i900 is inbetween the HTC and Apple with a two-tone black and silver finish. It feels a little like a plastic toy with average build quality. But the brushed metallic rear and the glossy front makes the overall appearance look very stylish.

Winner: HTC Touch Pro
While the HTC Touch Pro may look like an oversize candy bar, it should have no problem against accidental drops and bumps compared to the other two.

User Interface

Apple iPhone
The Apple iPhone 3G incorporates iPhone OS and offers an easy-to-use interface to access the various applications and settings. The applications and settings are organized using icons, with 16 on each page (and four standard ones at the bottom – Phone, Mail, Safari and iPod). Because the touchscreen allows for easy and intuitive use you can easily navigate the menus through touching and dragging with your finger. Up, down, left, right, diagonally and even multi-touch. 

HTC Touch Pro
Preinstalled with Windows Mobile 6.1 Professional, the Touch Pro uses HTC’s proprietary TouchFLO 3D user interface (like the HTC Diamond) that not only looks neat, but is also easy to use. The Windows Mobile Start button is located at the top left hand corner of the screen, while at the bottom of the is the main menu – Phone, People, Messages, Mail, Internet, Photos and Videos, Music, Weather, Settings and Programs. You can scroll the menu by touching and dragging your finger left and right.

Samsung Omnia SGH-i900
Like the HTC Touch Pro, the Samsung Omnia is also powered by Windows Mobile 6.1 Professional and features Samsung’s full touch based UI with Haptical touch feedback. The main screen comes with a widget bar on the left that allows you to access the time, date, music player, photo gallery, notepad and even games, simply by dragging the icon from the bar to the empty space on the right. Of course, if you prefer a more structured menu, just click the main menu at the bottom right of the display.
