Sony has taken the wraps off two high-end Clie handhelds that feature a clamshell design, integrated Wi-Fi and Bluetooth technologies, running on a Sony-made processor. The Clie PEG-UX40 and Clie PEG-UX-50 will become available in Japan in August and the United States in September. Sony Hong Kong says the two Clies will be available in Hong Kong soon after the Japan launch. The UX40 comes with built-in Bluetooth technology, while the more expensive UX-50 comes with both Bluetooth and Wi-Fi technologies. The UX-50 is the first in the Clie line to come integrated with Wi-Fi, but it is not the first in the market. In March, Palm introduced the Tungsten C, the first Palm-based device to sport integrated Wi-Fi. According to Sony, wireless technologies will become an integral feature in all its future high-end Clies, as it aims to increasingly allow consumers to access Web-based content and communicate using the internet. Masanobu Yoshida, Sony president of handheld computing, said in a press statement: 'We see beyond the 'tool' aspect of the handheld market.' Both Sony devices use version 5.2 of the Palm operating system, and feature a new design that resembles a miniaturised tablet PC with a screen that swivels around 180 degrees. Sony's Clie handhelds differ from competing devices with an emphasis on the multimedia experience. The new handhelds are integrated with digital camera, voice recorder, digital audio player and speaker functions - key attributes in all high-end Clies. Despite the change in form, the new Clies do not get a bigger screen. The colour screen has a resolution of 480x320 pixels, one of the highest in the market. Research firm International Data Corp says the market for handhelds has declined in the past quarter, with worldwide shipments plummeting 21 per cent to 2.45 million units in the first quarter. The Pocket PC camp continued to gain ground on the Palm-based camp. In the first quarter, Sony lost its No 2 market share position to Hewlett-Packard, which sells the popular iPaq series. HP's Jornada series of handhelds were discontinued after the merger. HP has about 18 per cent of the market, and Sony has just over 16 per cent. Palm maintains its No 1 position in the market, with 36 per cent. The new Sony devices differ from their predecessors in that all the key components were made by Sony, including the colour LCD screen, lithium polymer battery, charge-coupled device (CCD) sensor used in the digital camera, and processor.
