This has happened to me when I am out of wifi connection. But only then. I went to the Spotify boards to look for the answer, which involved having wifi connected.
frankenhooker: I went into Developer Options and set the processes to 4, instead of Standard, which so far has helped to eliminate the laggy processing. Did you wipe cache?
I actually practiced this process on my N7 because the LP update turned it into a plastic brick. I redid the clearing process and got past that No Command nag. Will see if the process enlivens the LP blues.
If you are notified of the OTA of LP for a N7, beware, it kind of ruins the device: check the posts:

My Samsung type batteries all love being replaced. How can a Motorola battery keep fresh after a year or more of use? Or, is it, battery dies near trade in time?
It will take some getting used, a non removable battery that doesn't need replacing. But, thanks to all for the battery inservice info. Appreciate the help.
