I have had Breezy installed on my box since a few weeks, and there is definitely a lot of improvement since hoary. Right now I have burned a CD-R with the distribution to migrate the lot of boxes I have at home. One of the things I do like with breezy is that everything fades in or out (ie. the screensaver) and that hibernate/resume works better than in hoary. Still, my hibernate problems still occur with my samba shares; I have to re-mount them every time I resume.
