The iMacs after 2012 have many disadvantages. I think I'll stick with what I've got. As long as I can find an external drive than can boot El Capitan I'll be satisfied with it. Doesn't have to be huge or super fast.
My long term plan is to build a PC that can be upgraded. I pick the parts. From what I can see, that is the best chance to avoid getting screwed by the tolerant, compassionate, saintly people of Silicon Valley.
