Just startd using Ubuntu myself a few months ago,
and despite tripling my memory footprint & number of processes,
i'd say i'm well pleased.
My only gripe would be that
they don't seem to go out of their way
to let th user know they'r atchely running Debian.
But all in all, i rckn Ubuntu could be Linux's killer app :)
