HTC Diamond 100 / HTC Touch Diamond P3700 / O2 Diamond

We don't envy the HTC Touch Diamond. There's a lot of pressure on this little smartphone; HTC executive Cheng Hui-ming has called it "the most important product for HTC this year," and of course, the Touch Diamond has been compared to the Apple iPhone. No...

The HTC Touch Diamond has a cool 3D interface and a beautiful touch screen. The Windows Mobile 6.1 smartphone also offers Wi-Fi, Bluetooth, GPS, and a 3.2-megapixel camera.

The Touch Diamond is sluggish and call quality is subpar. The TouchFLO interface has a bit of a learning curve, and there's no expansion slot.

The HTC Touch Diamond offers much in the way of sex appeal and flash, and it's certainly got a formidable feature set. However, we hope HTC resolves some of the performance issues we experienced before the smartphone is released in the States.

The HTC Touch Diamond for Sprint offers better performance and supports Sprint's EV-DO Rev. A network and multimedia services. The Windows Mobile 6.1 smartphone also features the cool TouchFlo interface and has integrated Wi-Fi, Bluetooth, and GPS.

While performance is greatly improved over the unlocked Touch Diamond, there's still some sluggishness. The virtual keyboard is cramped and may give some users problems. The Touch Diamond also doesn't offer an expansion slot.

The HTC Touch Diamond for Sprint brings some nice additions and improvements over the unlocked GSM version--most notably to performance. It's best suited for first-time smartphone buyers or light users, while business customers should wait for the Touch P...

We thought the Touch Diamond was going to be HTC's pièce de résistance. Instead, we were left wanting more. It looks the part of an all-round super phone, but it doesn't work like one. Hopefully, HTC can learn from this and make the next iterati

The HTC Touch Diamond offers a lot of features but falls short of delivering a sparkling performance.

We like the Touch Diamond much more than the HTC Touch, the company's first touch phone, and the improvements are everywhere. To start with, the Diamond is smaller, measuring 4.0 x 2.0 x0.6 inches, and easy to carry. The front is glossy black while the re...

The front is dominated by a 2.8-inch, 480 by 640 pixel display, which shows off the attractive TouchFlo interface. Below the screen you'll find a circular navigation pad surrounded by four physical buttons (home, back, start call, and end call). The butto...

The HTC Touch Diamond is available from Sprint for $249 with a two year commitment

At one time, HTC made handsets for other companies, but it is increasingly making a name for itself in the Windows Mobile space. The Touch Diamond has a high-gloss finish and the faceted design on the back helps give it its name. The quality of the plast...
