Ubuntu 11.04 was released on April 28 with a brand new interface and a couple default application changes. But all the talk is about Unity, that brand new interface. As one might predict, reactions are all over the spectrum. The Unity interface has taken design cues from popular mobile systems with the focus being on saving screen space and making everything readily accessible from within that limited space. It appears designers were shooting for easy and beautiful, but some users are finding adjustment during these early days a bit challenging.
