Here was what I wrote about Nova and Apex today:
Installed Nova and Apex on my Note and then added Facebook widget. The stock launcher displays the widget with space for a row of icons on the side. Neither Apex or Nova did so out of the box. I did not take the time to explore if I could fix this. I am going on the assumption that the stock ICS Touchwiz launcher is better optimized for this very high density screen. You could resize the widget but that isn't the same thing as displaying things optimized for the native screen resolution. Interesting that the Note is the same resolution as the Galaxy Nexus 7 but obviously at a much higher density. A higher density in fact than the iPad "3".
