Perhaps they received a hot tip about iPADS being packed
with explosives. <shrug>
The last several times I have flown TSA have expressed no
interest at all in my CPAP machine when there was a time it
had to be extracted and go through the swab test.
It has got to the point I leave the machine in the bag rather
than extract it. I'm sure a time will come when I will be yelled
at for leaving it in the bag when they switch up their
protocols again.
