Product: PalmOne Wi-fi SDIO card Price: $1,010 Pros: Works like a charm; smaller adapter size Cons: A little pricey If you own a Tungsten 3 or Zire 72 handheld, you can now get a wireless local area network connection, or Wi-fi. I tested a PalmOne Wi-fi SDIO (secure digital input/output) card with the Zire 72 and it was a breeze to install and set up. An Install Wizard guides you through the steps and, after a HotSync operation, the Wi-fi setup and virtual private network setup utilities and the Web Pro browser application were installed on my personal digital assistant. Tap the Wi-fi setup icon and the utility spots a list of Wi-fi networks in range. I selected a network and was connected within seconds. The application also checks for signal strength, establishes disconnect time and sets up WEP (wired equivalent privacy) encryption. Connected to the Web, I opened the device's installed Web Pro browser. It took about 15 seconds to load Yahoo! Mail's website. Web Pro uses a proxy server, which you can disable, that formats web pages to look better on the small PDA screen, but this function could delay loading times. While you can use both a Wi-fi and Bluetooth connection at the same time, PalmOne recommends disabling Bluetooth since it may interfere with signal quality. Wi-fi also saps a lot of power, so keep an eye on the battery life. Using the bundled VersaMail e-mail software, I encountered a few problems configuring settings for POP3 mail. After about 20 minutes of fiddling about with settings, I was able to send and receive e-mails. The card requires at least four megabytes of free memory on the handheld. Before using it, you must install software from either a personal computer running Windows 98 or its later editions, or a Mac running OS 9.2.2 or OS X 10.2.x to 10.3.x. Also, you must turn off the Bluetooth adapters that are built into both models. Overall, the card is a good investment if you already have a Zire 72 or Tungsten 3 because it gives you a better wireless connection than Bluetooth. However, performance is not quite on par with PalmOne devices with integrated Wi-fi. The older Tungsten C would probably be a cheaper and better option.
