Since manufacturers of several smartphones (like Motorola Q or Samsung i320) and Pocket PC phones (like E-TEN G500 or HP iPAQ hw6515) nowadays prefer to place in them some other features (like QWERTY keyboard or built-in GPS) instead of built-in Wi-Fi, and since many of these devices nowadays have only mini-SD card slot (that is too small to fit regular full size Wi-Fi SD cards), it may be of interest to many people to learn more about mini-SD card Wi-Fi card like the one from Spectec, that seems to be the only (!) Wi-Fi card in mini-SD format:

hp iPAQ hw6515とか使っている人には便利かも知れませんね！(といってもSDのWiFi持っていれば必要ありませんけど)
後は使えるデバイスってあまり思いつきませんけど・・・（ｗ 今後はminiSD採用の端末が多くなってくると思われるので、WiFi内蔵していないとかいう場合には有効かも知れませんね。
