one of our Maths teachers found these recently:
Interesting and so simple....anyone have a 3D Printer and some neodymium magnets?
For the love of all that is holy, do not buy any of these for your school if you still have non-SSD computers.
If I bought those here it would be less than an hour before someone stuck it to the side of their desktop "for storage" and then wondered why their computer stopped working.
Not sure if the magnet is only on the Tablet bit or if its two magnets?
Should come with a HUGE warning about SSD based tablets only!
Also has warning of using with a pacemaker... sounds great for using in Hospitals!
