well, I'm just going to wait til Monday, removing USB-C charging would be a stupid move for sure.probably they will keep the same brick design with the ethernet port in the power supply aka 24" imac
so it will be proprietary port with both charging and ethernet signal in it, but i dont think Apple will remove the ability to charge over usbC like we could in the last 6 years
Thing is, a laptop for me I not the primary computing device, I considered it a year or 2 ago, so I am far more intreated in what Apple has to offer with its M chips as I am going to replace my iMac in ~ 2 or so years with either a Mac mini or the new 27 replacement. And my M1 MBA is the perfect travel companion for me ...
