Wireless Platforms Aim to Amaze: Page 5 of 10

Windows Mobile supports multiple wireless networks, including CDMA 1X, GPRS, Wi-Fi, IR and Bluetooth. With native IPsec, L2TP and IPPTP support, and 13 third-party vendors providing products, Microsoft's VPN offerings are stronger than any of the other vendors.

Although the Pocket PC platform is well-accepted for PDAs, the wireless industry has some misgivings about Microsoft dominating this area, which explains why Nokia, Sony Ericsson and Siemens have banded together to use the Symbian platform for smartphones. Despite this resistance, phones based on Windows SmartPhone are now available, with more on the way.

Microsoft. www.microsoft.com/windowsmobileAlthough Palm didn't invent the PDA category--that distinction belongs to Apple and its Newton--it did make the PDA successful, and it still enjoys dominant market share. Palm is now split into two companies, with PalmSource delivering the OS and PalmOne in charge of devices.

Despite significant initial growth, the PDA market is stalled at about 10 million units per year, and Palm, like others, is concentrating on wireless platforms, including those supporting Wi-Fi, like Tungsten T, and cellular, like Treo 300, 400 and 600. The Treo line was developed by Handspring, but Palm recently acquired this company, which, ironically, was started by defectors from Palm. Despite lackluster sales of the Treo 300 and 400, the Treo 600 now appears to be a major contender in the smartphone market. Palm's greatest strength is the large number of applications available for the platform. The vendor also has a strong loyal following of PDA users who may gravitate to the Palm wireless platforms.

Palm claims more than 20,000 software titles, which it says is more than any other mobile platform. This is plausible given Palm's well-established PDA history, though you must research whether the applications you need are available, and whether applications that were written for prior versions of the OS will run on newer versions. If not, Palm provides a variety of development options, including C, C++, forms-based approaches, Java (J2ME with MIDP 1.0) and Visual Basic.
