Infosyncworld has an review of the palmOne's own Wi-Fi SDIO card for the Tungsten T3 and Zire 72. The reviewer concludes that the card is easy to setup, provides 802.11b connectivity within a good range, and offers solid security through 64-bit and 128-bit WEP encryption.
Edit: Palm Infocenter brings another review, which comes to a similar conclusion like Infosyncworld. It adds that the card is quite power thirsty.
After a *long* delay, the palmOne Wi-Fi card will finally be available starting on
3 September for $129 USD.
