DS / 3DS / Vita and Android consoles, GPD Win, are not there either.
Funny that there isn't a limit on the
number of phones you can travel with... Picture 3 in-spec smartphones with each having 1/4 of a keyboard that folds down from them in portrait mode which then snap together to form a full sized laptop keyboard with 3 nearly bezel free displays side by side. Maybe that will become a thing?
But - the limitations may be interpreted to dimensions AND being a 'smartphone'. In that case anything without telephony support would potentially fail. In that case, theoretically, a 4G Pyra could fly and a non-4G Pyra would not. A funny twist would be that your old no longer in service phone that you use as a miniature WiFi tablet and remote control could fly, but an equal sized tablet without onboard phone support could not.
Get to the airport. Check your 'checked bag'. Travel to security with your carry on. Find out your $$$ device flunks their test by whatever measure the security agent has been told to use. Then what? Your main bag is already checked and cannot be easily recalled so you can repack and you're in the middle of a security line.
Airport security services are going to wind up with barrels full of tablets, laptops, battery packs... I wonder if they'll keep them separate from the barrels of shampoo, hair gel, deodorant, baby formula and half drank bottles of soda.
If these rules get applied more broadly to places I fly, I'll be skipping the electronic kiosk for check in so that I can tie up an airline ticket agent's time going through my planned carry on devices one by one and declaring them OK or not OK. That is not an efficient solution either.
It will take some time for these regulations to get ironed out. In the meantime there are going to be a lot of very bored people on some very long haul flights. Physical book sales might skyrocket?
