The memory layout on the Tab 2 is a strange bird. The 8GB is divided into two partitions of equal size, and you will always see the internal memory and virtual SDCard being of equal size. You really only have 4GB to actually install anything programwise. With Ice Cream Sandwich, you cannot move apps to the ExtSDCard because of Google's far-seeing "wisdom" that said that we would not ever need more than what they gave us in the Tab 2. There ARE some apps that will allow you to move some game files to the ExtSDCard like GL to SD(Root) and Directory Bind, but there really isn't a long term solution yet on how to move apps to the ExTSDCard consistently without need of special apps. I imagine that it may take a major ROM tweak that will allow this function. There is also a 1GB dedicated cache directory that needs to be cleaned ever so often otherwise Google Play will not allow you to install anything once the cache is filled. There are a number of utility apps available in the Play Store that will optimize memory and clear the cache...
