My impression with Fedora 18, as I had mentioned in the post with I opened and talked about it, is that it works right or wrong according to the desktop using. If you are using Fedora 18 with Gnome or XFCE really it's a bad experience, has a poor performance with these two desks, especially with XFCE.....
But if you use Fedora 18 with KDE or LXDE desktop experience there is really very good, almost excellent. Go you, to know why, but if they are looking for a very good experience with Fedora 18, I strongly recommend using KDE or LXDE .... Best regards.-
