Apple closed a number of U.S. retail stores last week, and is closing another half dozen more this week for undisclosed renovations. All of the stores closing are street-level locations and the most likely reason is to retrofit the stores with Apple's new security grate system. Apple closed a number of other stores last fall for the same reason.

Last week, Bethesda Row (MD), Village Pointe (NE), and Crocker Park (OH), and perhaps others were all closed, apparently for the same reason.
