Actually, the average cellphone has a 32bit ARM chip running at 200mhz...good cells have much better than that.
That is easily more powerful than not only the Apollo on board system but more powerful than the systems on the ground as well....and by a large margin.
That’s why I’m getting an Iphone - not for the phone part (keeping Verizon for that) but for the apps - a handheld computer has been a dream since the Jetsons days (also the personal flying car but that can wait).
