SanDisk's SD WiFi card is - if nothing else - a technical tour-de-force. I'm still impressed that a fully-featured 802.11b adapter is now about the size of two postage stamps laid end-to-end. What's not impressive, though, is the extremely poor throughput and continued slip of the promised Palm OS drivers.
At this point, the SD WiFi has some growing up to do. In the meantime, heavy wireless PDA users will be better served by CF adapters or devices with built-in WiFi. f letting Aerialix do the cutting, soldering, and shrink tubing.
