Apple ignoring feedback
Schools claimed students found the iPads too difficult to type on so... Apple does nothing to improve those crappy plastic keyboards for the iPads.
You could make a better iPad keyboard by having two hinges on it to hold the iPad and having the bottom of the keboard slide out backwards between them for mobility.
If Apple are worried about these improvements cannibalising sales of the MacBook Air and Pro, go dobe the path that Dell is taking with it’s XPS line and remove the bezels to get a bigger screen in a smaller device. The 13” models could become 15” models and the 15” models could become 17” models with the same form factor.
