I think ppl make assumption its gonna be very heavy because in the 1st ads we see how the iPad can be pulled off the Magic Keyboard very easily with one hand. Lead to believe the bottom part must be real heavy to stay in place like that.But check out the 2nd ads ( the real world usage )You still need to hold the bottom part to open the case and pull the ipad to keep it in place..I don’t work for apple so i dont know the precise weightFor some reason even Apple don’t provide weight for current smart keyboard and folio officially on their website..But i dont think its gonna be that heavy people led to believeWith that double hinge method and limitation to 130degree, the bottom part does not need to be as heavy as the ipad itself ( unlike bridge keyboard ). The whole case can still use the same material and plastic internal keyboard structure as the current smart keyboard.What we don’t know is how heavy that metal hinge construction, trackpad and that extra thickness (looks thicker than the current smart keyboard based on the image)Current 11” smart keyboard is 295 grams, my guess the magic keyboard is around 400 - 450 grams for the 11”Cant speak for the 12.9”I could be wrong.FyiiPad Pro 11”: 468 grams Brydge keyboard for 11”: 550 gramsSlim Folio Pro for 11”: 552 gramsedited: grammar.. sorry English isnt my first language
