-With 7.3 full install never finished because anaconda gave me a bug report with packages containing python files.
-KDE at times was slow as hell. Maybe it was the KDE version that had the memory leak problem.
-Install was much slower
-It seemed to be a bit slow on loading apps.
7.2 on the other hand took about 20 minutes to do a full install.
From what I can tell it runs faster.
Now I just need to update my kernel, install the latest version of KDE and Gnome, and I use the CDROMS from 7.3 for apps that 7.2 doesnt have.
