Is Fedora 7 an upgrade over Fedora Core 4?

[Karl Larsen <k5di@xxxxxxxxxx>]

   It's been 2 days since I loaded F7 on this computer with a 160 GB HD 
and so far I have got one application (Thunderbird) working after being 
told which lib file to yum in. This should have been in F7 by default.

   I am still trying to get Skype to work. I have tried a lot of things 
but still not the intuitive things used here on Fedora Core 4. They 
don't exist on F7.

   There are some harder things I must have working at least as well as 
here on FC4 or I will just stay here. Getting F7 to do things is a pain. 
I think for my way of doing things I better drop back to Red Hat 9, or 
even 7.
