My longest delay was taking a bag with many zippered compartments, containing chargers, earphones, ipod, usb cables, and reader. Everything came out, then they scanned again - discovered they missed a cable, etc. 20 minutes later, we were done.
So looks like:
1) Rules inconsistently applied (no surprise)
2) You are probably ok leaving Ipad sized devices in your bag, until you are asked to remove it :-)
