"According to Kaspersky, 21 percent of Brits believe a magnet can erase a smartphone. (This might be true if you used that magnet to smash the device into millions of tiny pieces.) That sound you can hear is a thousand IT professionals slapping their faces with the palms of their hands."
This is the fault of the IT industry.
We had, and still have, a lot of HDD's out there which users have always been told, since the days of floppy discs, you shouldn't put anywhere near a magnet. Fair enough.
We now have a lot of Solid State Storage which as far as the average user knows is just a faster sort of disc drive.
The average user doesn't care any further than they do the same job. Nobody has explained, and why should they?, that they are compleatly different technologies and magnets arn't an issue with Solid State.
It wouldn't suprise me if 21% of Brits in the age range asked were brought up with dire magnet warnings so why should we expect any other result?.
Very very few companies do any IT training unless its for software.
If you doubt this try spending a day with your first and second line support teams and see how ignorant the majority of staff are when it comes to hardware.
