"As for Unity; its incomplete, buggy and complicated." -- four lines later: "The non geek will love Unity. Its simple to use [...]". The author fails to be consistent even in a single paragraph. Even the post's title contradicts its content.
Note the present tense in the first quote and the future tense in the second. Unity will be a very user-friendly system once they fix more of the bugs.
Indeed, look at all the work canonical spent into speeding up boot and how it a couple of releases later regressed heavily almost back to where we started. Stories like this gives me little faith in Canonical managing to keep on improving Unity.
