An anonymous reader links to an exhaustive look at the latest Ubuntu, running at Tom's Hardware. "The new Unity interface is broken down into its individual elements and explained ad nauseam. Overall the article is objectively balanced, the author does a good job of pointing out specific design flaws and shortcomings instead of complaining about how Unity doesn't work for him specifically. The walkthrough of the uTouch gesture language is exciting (wish I had multi-touch), though a full listing of keyboard and mouse shortcuts come in handy, too. Towards the end of the article there are benchmarks between Lucid, Natty with Unity, and Natty with the Classic interface. The performance of the Unity interface isn't bad at all, but that kernel power issue does rear its ugly head."
