The last time I flew out of SeaTac airport, after my bag went thru x-ray, the TSA made me stop, take out my Kindle, and then put it and my bag in separate bins, and have them x-rayed again, just as if the Kindle was a laptop. When I flew through SeaTac again today, they were announcing it to the line as we approached the machines, that we had to remove our Kindles.
And yet, the TSA has announced that Apple iPads can stay in your carryon bag, and don't have to be seperately removed and screened.
What a coup for Apple! "Use an iPad, and avoid some of the TSA's dumber security theater".
