In the aftermath of the theft of a plexiglass display case containing 42 iPod nanos from the Twenty Ninth Street (Colo.) Apple store, displays at other stores have been modified to secure the 30 pound cases to a table. Boulder police say store employees noticed the display case missing at around 5 p.m. earlier this month, but didn’t see any suspects take the 2’x2’x6″ box. When originally installed, the display case wasn’t secured in any way. Recent visitors to stores where the nano case is still on display say the cases are now secured to the table in some way. The 4 Gb nanos were worth about $8,450, according to a police report.
