While the desktop version of Ubuntu is basically solid, there are still some issues. We’re not thrilled with the Dash (dashboard) search functionality, but at least it can be turned off. The Unity interface has windowing behavioral changes that we found odd. There is a default global windowing policy that spawns child windows that are subsidiary windows of the parent, but the child windows don’t behave like the parent. Also, underneath various Web apps is Ubuntu’s own browser, one that’s comparatively immature compared to Chromium or Firefox.
