As somebody who manages thousands of iPads and hundreds of Mac's in a few schools I find this very weird. Who is this aimed at? Apple are really out of touch when it comes to Education and the Mac.
If they aim it at a Teacher the 128GB is too small, once you install Office a few other apps and put say a few videos on there and some other content its full and your updates/patches fail and user complains of disk full message.
If the aim it at students for use in say a laptop trolley the keyboards would get broken and that would be eye watering to repair, so that's a no. Education need cheap, quick repairable devices. iPads work great in this respect as they are easy to manage and less to break compared to a laptop (no hinge, keyboard, trackpad etc)
If its aimed at university students I think they will have the same issue a Teacher would, the 128GB will fill up to quickly.
I just wish Apple would take the Mac and Education a bit more seriously, I love them they are way easier to manage than Windows devices and have other advantages, BUT you cannot order a Mac with a wired keyboard and mouse anymore from Apple, you have to have worse looking 3rd party ones. On what planet do they think wireless keyboards and mice will be a good idea in an IT Lab? I just wish somebody at Apple would actually fully understand Education needs and cater for them properly.
