When we last saw the AirStash, it was keeping its mystique about it and refusing to disclose any salient details beyond the fact that it'll function as a wireless SD/SDHC card reader. Today, the fog of war is lifted with the news that the AirStash is now officially on sale for $99.99, and will come with a battery good for five hours of continuous data streaming. Marketed primarily at iPhone OS devices, it creates a wireless network that allows any WiFi and browser-equipped computer to access the storage cards within it. The UI is built around HTML5 and recharging is done via a USB connection, which also turns the AirStash into a simple SDHC card adapter when plugged in. Chec
