Hi,

"Unlike previous releases, the developers are planning to use a full
Fedora desktop build which will boot into Sugar, the open source
learning platform used on the XO laptops, and also give users "the
option to switch into the standard GNOME install instead." The option is
mainly intended for older students, such as those in high school."
