When I installed it, everything worked fine, but then it started resorting back to the "Vista-like" security that the beta was. It is a resource hog as well (congrats). I couldn't get on the wireless at all as well because that didn't work either. When i was using compiz, the graphics were slow, lagging or even stalled!!!! So now I am reformating and re-installing 7.10. I HATE 8.04!!! It is horrible. It takes 20 seconds longer to boot, compiz doesn't work very well at all, virtualization is a blow too! I can't even get VirtualBox to work. If you have any suggestions, I will be happy to tell you that I am not going with Ubuntu 8 until 8.10 comes out.
I have never had a problem with 7.10 so It is my choice. NOW FIX 8.04 and I will be happy to upgrade.
