#82, #85: For me, the reinstallation was quite an easy-go. Nothing messed up, most of the settings remained to work as they did previously. The only things I had to install again were Opera (internet browser), Nvidia drivers and there were some minor tweaks for the UI itself - I am now using Unity instead of Gnome 2. But I don't use Unity's dash a lot and I stick to using Synapse launcher which is much faster and usable - at least for me.
