How about this -- remove the "Pro" from the Apple computers that have it in their names, since it is unnecessary. This means the Mac Pro becomes the Mac and the MacBook Pro becomes the MacBook. Then take the entry level models in all the lines and add "Junior" to their descriptions. So we get:
13" MacBook Pro becomes 13" MacBook Junior
11" MacBook Air becomes 11" Macbook Junior Pilot
Mac mini becomes the Mac Junior
