I bought the SanDisk WiFi SD [idlesandiskwifi, sandiskwifisd] card for my Zodiac, but I've found that I never use it. As a matter of fact, I never even carry the WiFi card with me. Why?
rocks. Even though Bluetooth is slower than WiFi, it works perfectly with my cel phone as well as the Class 1 Bluetooth Access Point I set up on my Linux box. Since I always carry my phone, and I have an unlimited data plan, I have ubiquitous internet access with my Zodiac.About the only time I use the WiFi card is when I sit on the far end of the sofa in my living room, which is just outside the range of my Bluetooth Access Point.
