What's wrong with #Android 4.2 on the #GalaxyNexus, read on

• Closing apps by swiping them away in recent apps list is laggy.  
• Turning of the screen takes like a second. How did this get past testing at Google? 
• In Camera, screen rotation takes a full second every time! This can be a problem if you want to take a picture of something very quickly.  
• Chrome scrolling and performance still as nasty as before. 
• Google Play still laggy to navigate. Google Play Music has very buggy animations. 
• Lockscreen widgets are super ugly and the camera widget takes ages to load. 
• Why is the Navigation UI also stuck in Gingerbread era?

4.2.1 should be able to address some or all of this. Waiting.
