What on earth does "(not) compatible with apt" mean? If you point yum 
& apt to same set of repositories there's no problem using them both on a 
same system interchangeably. Not compatible as in "can't use the same 
repository metadata" is true at the moment (though work is being done to 
resolve that issue)

Uhh, please... its seconds vs minutes, not hours. And even the "50 minutes
to calculate dependencies" mentioned in Warrens mail is under specific set
of conditions, not something that happens for your average "yum install
foo" operation. For a normal package installatation there's no much of a
speed difference. For big upgrade (like RHL 9 -> Fedora Core 1)
apt wins hands down but still lets keep the facts straight...

..until you fix the situation.
