It will work, but I question it's legality. Yes, I know it has no effect on the plane, but it's still illegal. They made me turn off my wireless Kindle on the flight. I even had the wireless turned off, but they still made me turn it off. I have no clue how an e-reader with wireless turned off could possibly interfere with flight instruments even in a theoretical way, but apparently it can. Strangely enough, I was allowed to have my phone turned on as long as it was in airplane mode. Kindle must be off though.
