Well the ability to hide crap works good. But the reorganization was a deorganisation. The UI is a jumble of different styled icons, with the polldaddy and upgrades. The icons without them look somewhat pretty. But WP is slowwwwwwwwww! The custom buttons look awful and the combobox up there is a dumb place to put it. The tabs I use to switch dashboards is also gone.
I dub WordPress 2.7 the Windows Me of blogs.
