It seems that in some ways this list may have lost it's focus. If I'm wrong, please correct me. Isn't Fedora here to explore the latest and greatest? If this is true, at some point two releases a year might not be enough based upon advancements. If someone is expecting a relative distro without change and they don't want to pay the support costs, they should stick with CentOS or Ubuntu TLS - correct? Speaking about incompatibility, isn't the only guarantee is that a kernel at the same level, regardless of distribution, will function exactly the same?! If you want to move from, say, KDE3 to KDE4 you have to upgrade your system because drivers and libraries are hardly ever forward compatible. If you want to move from the ext3 to the ext4 file system you must upgrade your system?! So, what this person is saying is that - I'm going to stop using Fedora because it's constantly moving forward and I want to live in the past! Thanks, Gene Poole
