i think you'll find that even an advanced user may consider that they could conceivably drop the unit. if there was some sort of plastic "lock" so that it was impossible for the screen module to drop out without extreme force, then you would be fine.
i think you should do some calculations to see what kind of strength magnet would be needed to provide "anti-shock" level of attraction, based on the weight of the components. i see "150 G" shock-force on hard drives, normally, so that i assume would be a good number to start from.
so now you would need to check the weight of the LCD plus its case and PCB, then see what size neodymium magnet *at each corner* would be sufficient to provide 150 gravities (10Nm) of attractive force. that's 1500 Nm. i think you'll find that the magnets needed are far bigger than you imagine might be needed.
The heaviest screen we would use weighs 66 grams.
