Summary: I did a lot of research before purchasing a tablet. Every time I found one that I liked it was missing some feature. The Samsung ATIV filled them all. Some of those key features are the(FULL SIZE) USB and micro SD slot. Don't like the available memory...expand it with the micro SD slot and still have a usable interface. NICE. The other feature is the battery life. It never dies. I used it for three days and still had 30% remaining.
