Everyone likes a pretty face, and that is why, despite the lofty price of HK$3,730 for the Visor Prism, it is still flying off the shelves in Hong Kong and the United States. With its 16-bit LCD screen capable of displaying more than 65,000 colours, the Prism has a look that turns heads on the MTR. Unfortunately, the pretty face does not come in a small, black dress. The Prism is chunkier than the original Visor. The extra bulk is on the back, which is thicker and curved at the bottom - the only part of the case that has been significantly restyled. As a result, the snap-on cover cannot snap on to the back. As with the Platinum, it is available in only one colour - metallic blue - which is not the best colour for a fat PDA. Like all Visors, the infra-red port is on the left side of the PDA. It would be better if it was on the top the way it is with Palm Computing handhelds. The stylus is handy, and both ends screw off the polished metal body. The bottom tip conceals a reset pin while the top end unscrews to reveal a tiny Philips screwdriver. Very cool. If you put a Palm IIIc and a Prism side by side, the displays have the same brightness and contrast. If you did not know the Prism had a superior 16-bit display over the IIIc's eight-bit one, you would never know the difference. The Prism is the only Visor that uses a new cradle because of the thicker case and plastic fin at the bottom. You can take the PDA out of the cradle without holding on to the base. The power cable for recharging the battery plugs into the USB (universal serial bus) connection, not the AC adapter. This requires you to pack both the cradle and AC adapter when you travel. It takes about two hours for a full charge of the batteries, which can last nine days of usage. The Prism, as with the Platinum, is equipped with a 33 MHz Motorola Dragonball VZ processor, while the Palm IIIc uses a 20 MHz Motorola Dragonball EZ processor. While the difference during day-to-day tasks is minimal, the Prism is a little faster when performing file searches. Graphic: prismgwz
