Well, since I couldn't find an answer online, I went to the nearest AT&T store to play with one. The device only has one partition, meaning that all apps, and downloads will be installed to the primary partition. There is only about 8gb available to the user, unless you root, and remove the bloatware.
Many devices claim to have "X" gb of storage, but it is only usable for music, videos, etc; not apps. The ZMax 2 allows this storage to be used for apps as well.
