My laptop is old, but not ancient. It could run Gnome fine, but I prefer
Xfce. I try to avoid Gnome dependencies whenever possible, mostly because I
want a fast system free of unnecessary cruft.

Concerning software: I believe Xarchiver is being worked on. I'm not so sure
about Xfburn, which is woefully underfeatured. Currently, the only
maintained GTK/Gnome CD/DVD burner is Brasero. AFAIK, both Graveman and
GnomeBaker are currently unmaintained. Brasero comes laden with Gnome
dependencies.

I'd prefer if software choices were left up to the user. The default Xubuntu
Feisty install is quite usable.
