So I tried RedHat 7.3 today
Well to cut to the chase, I thought it was sucky compared to RedHat 7.2. I put it on my laptop today and it appeared as if it had lots of bells and whistles. I didn't really see any improvements. I saw lots of disappointments. One thing I didn't like was no gnome desktop. It was just Nautilus on top of Gnome Libs. I tried to re-install Ximian but Ximian installer didn't recognize the distro that I was running. The RedHat Update Monitor looked cool but didn't appear to work, just gave a "Host not Found", which was really wierd. I pushed it and pulled it and it's not a great improvement, wait about a month and then try it.
