Umm, if you mean using it in the Zaurus, that\'s probably going to be more trouble than it\'s worth: this is a PCMCIA card, the size card most notebooks accept, and not a CF card, which the Zaurus accepts. Many CF-to-PCMCIA adapters exist; I don\'t know if one exists to go the other way, but if so, it\'s going to be rather bulky and awkward.
I think what you are looking for is a CF WiFi card...
