not so sure about that! First, ubuntu introduced me to linux
and i love the distro. Second, it's stability since 8.04 has been
questionable. Personally i think [also after a long chat with one of
their xubuntu developers] i have my concerns about their workload with
the 6 month release cycle... Fedora have the same problem.

For linux to compete effectively at a high standard they need more
cash and 6 month releases will be testing and that the biannual
enterprise versions will be the standard stable release.

I just trying out Centos and Debian at present on my spare machine.
I'm still on 8.04 and seriously wonder if 10.4 will as stable.

Time will tell... but i'm giving up on 'cutting edge' releases on any distro.
