HTC teased us with a new product launch a month ago.

Well, they did exactly that on the 15th of September in London with launch of the Desire HD and the Desire Z.

Desire HD

The Desire HD is modification of the HTC Evo 4G, the first WIMAX phone which is a US only device. The Desire HD is nearly identical in technical specifications to the Evo 4G apart from the obvious omission of WIMAX. Added technical enhancements include an 8 megapixel camera with dual-LED flash and 720p video recording, Dolby Mobile, and HSPA+ data with 802.11n WiFi.

The hardware build is, however made from a single block of aluminium(unibody design) with a side slot opening battery cover. The kickstand present on the Evo 4G is not incorporated into the Desire HD. The latter move makes the device a slicker looking machine. Android 2.2 (Froyo) is the lifeblood of this device with added HTC Sense UI.

Desire Z

The Desire Z has a similar screen size to the original HTC Desire with one major hardware alteration-the inclusion of a QWERTY keyboard. The processing power of the Desire Z done by an 800Mhz Snapdragon processor rather than a 1GHz processor found in the original desire. There are no physical buttons on the screen apart from a modified optical track button. The ‘Z’ monicker is added as a nod to its unique Z-shaped hinge mechanism. The screen does not tilt as on the HTC Touch Pro 2 or Nokia’s newly announced E7. The Desire Z’s US counterpart is the T-Mobile G2. Whilst the G2 will run on a non modified version of Android 2.2, the Desire Z will include the HTC Sense UI.

Initial impressions

The Desire HD and Desire Z are worthy additions to HTC’s already strong product portfolio. It certain provides a greater variety of form factors. Those interested in an Android device with a full physical QWERTY keyboard will certainly be curious about the Desire Z and those wanting greater screen real estate will look to the Desire HD.

Where does this leave the original HTC Desire? Its sales may decline somewhat with the introduction of the Desire HD and Desire Z. However, if priced well and if carriers provide an attractive package with the original Desire, it may continue to sell well. The original Desire’s design cues are different and may still retain its appeal. That said, spec hungry users are sure to go for the Desire HD. The fact is this: Those interested in buying a HTC Android device have more choices than ever and this is likely to increase with HTC’s ever growing product portfolio.

There is certainly no compelling reason for existing HTC Desire owners to change over to the Desire HD or Desire Z. These new devices are variations of a similar theme and are not a quantum leap in terms of technology. HTC has certainly more devices up its sleeve and there will be plenty more desirable devices to come from this prolific mobile device device manufacturer.
