I have been playing around with one for a few days (my mom got one and asked me to help set it up). She had an adapter that allowed full size SD cards to be plugged in. I was able to get Raw Droid (or something like that) that allows you to preview the RAW file and save a JPEG version. I was then able to get a basic photoshop app that allows basic cropping color corrections, sharpening/softening, and boards to be applied with a direct upload button.
I tried to plug in my sd card and thumb drive at the same time to this adapter however it would only read one at a time, but I did find another adapter on Amazon that says it will read multipule devices and allow you to transfer info from one to another. This is one of the reasons I was looking at this tablet, I wanted to be able to leave my big 17" laptop at home and just travel with tablet and external hard drive, and be able to transfer or copy images from the SD card onto the harddrive using the tablet as the middle device.
Whats everyones take on this tablet.
