Hi
http://www.linuxbsdos.com/2011/05/28/fedora-15-xfce-review/
"This article presents a review of the Xfce spin, and it is the first
for this edition of Fedora on this site. Fedora 15 sports several new
features. Some are not particularly relevant to a desktop user, but
others are. Those will be noted in the appropriate sections of this review."
