If you’re like me, you thought the AirStash was a mustache that floats in the air, like those seed things in Avatar, only not glowy. But the AirStash is actually a USB key with built-in SD card slot that can, in a few seconds, create a private hotspot that allows you to share the media on the SD card with anyone within Wi-Fi range.
The device costs $99.99 and can store and display images, docs, presentations, and contact info. For example, you can take some shots, put the SD card into the AirStash, and view the photos on your iPhone or iPad. Easy peasy.
