I had lots of bugs with Ubuntu 12.04 64bit but I liked the screenshots on distrowatch. Hence I gave it a go. Install was only possible via live - gnome session and my username was not taken. But hey all the rest is perfect. It looks good and I haven't found one single bug so far!
Very nice (clean) linux desktop. Runs very well from DVD (much better then many I have tried before). Harddisk instakllation is also easy. No distro if you want 20 programs to do the same thing. Comes standard with all media support (file types) to view YouTube etc. out of the box (fresh install)
