Not much else to say but if there are SD Card or USB Flash Drive (and to a lesser extent Micro SD) adapters for iPod Touch 4G. I know there was that "Zoomit SD Card Adapter" but that is seemingly unable to find and possibly discontinued.
no computer needed if you're connected through its own wifi.get the app if you have the hardware.Well okay. Just a few questions...
Is there any file process (moving, copying, document reading, ect.) that HAS to be done on Computer, not iPod Touch?
Does it stream well from a SD Card?
Can I use a USB-SD Card adapter (USB Flash Drive --> SD Card --> SD Card Slot) or Micro SD to SD Card to stream video and will it work well?
A usb adapter doesn't exist, and if it did, I doubt Apple would even support that kind of feature.
