Yeah, but remember, your Kindle is a much bigger threat to the navigation system than the 30 or 40 cell phones in people's pockets that they forgot to turn off. Plus, reading a Kindle might distract you in an emergency, which is why they don't let anyone read books or magazines during takeoff and landing either.
I was under the impression that the cell phone shutoff was to prevent the towers from freaking out about dozens of phones coming in & out of range at 650mph+.
I was under the impression that towers had some type of signal baffle to prevent reception from devices a certain number of degrees from the horizon.
I have no merit or citation to exert with this claim.
I've heard that claim but I'm unsure why airlines would inconvenience their customers for cell providers.
I have never been told to put down my book or magazine during takeoff or landing, or ever heard an attendant ask anyone else to.
Neither have I. That's why the flight attendants insisting that I have to put away my Kindle during takeoff and landing "to make sure I'm not distracted during these safety-critical times" is so absurd.
You should make a fake book cover that you can slide your kindle into. If you hide the bezel and only show the e-ink screen up flush with a page-cutout it just might work!
