Already I like what I see in Xubuntu 12.10.
The new Xfce 4.10 desktop environment with a network-friendly Thunar file manager
Nice defaults and design (which you usually get in a distribution's "native" desktop environment but not so often without it)
What I don't like:
Onto the next ...
So I'm in the live environment for Xubuntu 12.04, which aside from the ugly wallpaper (including every alternative wallpaper on the ISO image) is a great-looking and -working Xfce 4.8 desktop.
My main mission in running the live distro from a USB flash drive: Checking networked-filesystem support in the Thunar file manager.
So far I'm using FTP in Thunar to write this post. And I didn't need the Gigolo helper program to open the FTP site and create and save the file.
That's a win.
After a few false starts, I also got Thunar working for sftp connections.
What I "forgot" to do originally when trying to start an sftp:// connection in Thunar was to specify the port number when I opened it up. Here's how I did it:
In my case, that port number is 2222, so it would be something like this (I'm using a "fake" URL for demonstration purposes; use your real URL and real port number to make this work -- I can verify that it does work -- and you don't need Gigolo!):
