Motorola has unveiled a range of wireless devices for the second half of the year, including a BlackBerry-like phone with a full Qwerty keyboard.

The Motorola Q is based on the ultra-thin design of its popular Razr phone and is roughly half the weight of other Qwerty handsets. It uses Microsoft's recently launched Windows Mobile 5.0 software.

The company also unveiled its Razrwire sunglasses that offer wireless hands-free connections to Bluetooth-enabled devices. In partnership with Oakley, the glasses will be available in early August.

Motorola also launched Ojo, a video phone that supports a greetings and mail, and Rokr, a family of music phones with dedicated music keys, music player interfaces, extensive memory and long battery life.

But some analysts questioned Motorola's strategy. "It is interesting that the long awaited iTunes phone has been further delayed," said Jerome Buvat, strategic business consultant at Cap Gemini Telecom, Media and Entertainment.

"And there is a growing demand for simple phones, so I am not sure that pursuing a cutting edge phone strategy is the right way to capture market share. "
