Toshiba has announced full-sized 8 GB, 16 GB, and 32 GB SD memory cards that can shoot thumbnails over to your Android device for a quick preview simply by tapping your device to your camera. 16 thumbnails and available remaining space are shown through the dedicated Memory Card Preview App, though you'll still need to pop the SD card into a computer to get full access to the pictures. As neat as the mash-up of SD and NFC may be, Toshiba announced a Wi-Fi-enabled SD card that sounds decidedly more useful.
