Pff I switched to fedora 10 a month ago because Ubuntu didn't have eclipse 3.4 in it's repository but I'm starting to have second thoughts.
1. It's freaking damn difficult to make a damn share. At least the first time.
How do you do it in ubuntu you say ? Right click and select share and click a nice check that allows guest accounts to check your share.
How do you do it in fedora ? Well you install samba. That's ok. You then have to configure samba a bit to add some shares and stuff. That's ok. Then you have to figure out that the firewall is blocking the smb port, normally I wouldn't have any problems with on a server but this should not happen on the desktop.
2. Printing
Why the heck does Fedora ask me to enter the smb address of my network printer and can't it detect it like Ubuntu / OpenSuse / Mandriva ?
3. Packagekit
Yum comes to the rescue. The add/remove interface for package is cute but the search functionality is retarded. You basically need to know the package name.
