I've seen people likening this transition from when Apple went from PowerPC to Intel. The figures being tossed around, from what I've been reading, was a 75% drop of resale value from those PowerPC macs after the Intel switch. That's a scary prospect for anyone looking for a 2020 MBP now. I'm not okay with plummeting resale value in 2 to 3 years because I always sell my devices when I purchase anything new -- and I want the most I can get for it.
On the flip side, some people are saying these are the last Intel Mac machines that can run Windows and that, in turn, would drive the second hand value for these systems.
We just have figure out which of the two scenario is more likely. But at this point we're just speculating; I want much more concrete information before I commit money on the table for a 2020 MBP. The back to school sale also makes this decision hard. At the moment, I think I'm going to go the used MBA route to put as little money on the table while I examine how the ARM Macs do.
