The article focuses on personal digital assistants and smart cellphones. At the top of the list of popular add-ons is Bluetooth, the wireless Personal Area Network connection we have been watching for the last five years. Bluetooth can get rid of wire tangles to headsets, cell phones and other gadgets, and Wi-Fi can do the heavy data handling. Sharp is still developing clamshell designs like the Zaurus SL-C750 and Zaurus SL-C760, two new Linux-powered handhelds it announced this May 2004, but so far only for distribution in Japan. All however is not lost for those of us who want the micro-laptop feel. Sony, the Palm OS alternative, recently announced just such a device, the UX50 CLIÉ. Not only does it satisfy my craving for keyboard on a clamshell, this 6.2 ounce palmtop packs everything you could ask for into its 4 1/8 by 3 1/2 by 23/32 inches. To hit some of its highlights, it's got: 802.11b and Bluetooth, a 0.3 MP digital camera, voice and video recording, MP3 playback, a backlit QWERTY keyboard, built in Microsoft Word, Excel, PowerPoint, and PDF files viewing. Naturally, all that comes at a price, and it's not cheap--$699 for the UX50 and $599 for the UX40, which comes without 802.11b but still has Bluetooth. Meanwhile back at Palm, an update to the Tungsten line was announced, the T2, which is available and selling for $399, gets a colorful new transflective display and Bluetooth connectivity. As promised, Microsoft released Pocket PC 2003 on June 23. There's an improved Connection Manager to make setting up devices and getting on networks easier and more flexible, and a new image viewing/editing application as well. The upgraded operating system lets programmers take advantage of features in Intel's X-Scale processors, and adds Pocket MSN and a new application for viewing and editing images, called Pictures. Pocket PC 2003 moves the OS towards Microsoft's .NET strategy.
