Your inductive charging tray tables are terrible for my magnetic tapes and floppy disks. Also, where does it get its energy from? It's much more efficient to walk around with wearable solar panels or to embed them directly into the devices. It may not work well on the north pole half the time but batteries aren't very conductive in those environments, anyway.

When was the last time you walked around with a magnetic tape or floppy disc?

Now - what happens if you put your wallet full of credit cards on it?

To be honest, magnetic strips on credit cards are redundant in a fair proportion of the world as well, especially Europe, although with a notable exception of the US which seems to be seriously lagging behind in this area. I live in the UK and it has easily been over 6 years since I have been anywhere where the magnetic strip has been read rather than using chip & pin (EMV).
I visited the UK late last year and can confirm that your card readers can still read the magnetic stripes on our outdated American credit cards if they absolutely have to.
Unfortunately both types die with exposure to magnetic fields - I accidentally too mine into an MRI scanner. This may not Oruro at a lower field strength with the chip type however.

Wow. That was a bad one, sorry, and I can't edit it. It was supposed to say: Unfortunately both types die with exposure to magnetic fields - I accidentally took mine into an MRI scanner. This may not occur at a lower field strength with the chip-type card however.
I'm pretty sure he was being sarcastic.
There isn't enough upward facing surface area on your body for solar cells to power anything non-trivial. Also floppy disks?!?
Power usage is going down with every generation. A few watts is quite a bit for a machine with an e-ink display.

For others, maybe nothing but charge sustaining purposes at first.

Guess we're not going to be able to work with our SX-64 portables on planes anymore.
