Hi all,
I  installed and used F11 Preview and these are my first impressions.

- The system runs ok, I did not have any big problem. I have to admit it looks more stable than I thought.

- Boot time is a bit higher than the advertised 20 seconds. It goes from 30 to 50 seconds. I rebooted the system about 5 times. It is still acceptable. One question: when the system boots and the progress bar is displayed there is no Fedora logo. Is this correct?

- The only problems I had so far are related to the Package Manager. Sometimes when I modify the checkboxes in the repository list it freezes or it shows an eternal "Waiting in queue" message. This happens sometimes even if it is the first thing I do and even if all the update requests are done. I have to say, it is slightly less usable than my experience on F9 (I missed F10, sorry!). Once, after 10 minutes a "yum locked" window popped up.

- I tried to install KDE (both in terminal and using the package manger) but I continuously get an signature error, which surprised me. See the following:
Package kdelibs-common-4.2.2-12.fc11.x86_64.rpm is not signed

[root@squarz ~]# ^C
[root@squarz ~]# yum install @kde-desktop
