@maflynn's question is reasonable.
I've tried to avoid a knee-jerk reaction to the new MP announcement, but now after a little time pondering it, I'm just left feeling sad that the dream of an affordable upgradeable Mac does not seem like it is going to happen again. As Windows is simply not a viable/tolerable option for me, this forces me to start planning for a switch to something like System76.
I'm sure Apple (or anyone else) doesn't really care about that sentiment, but it's sad because it doesn't have to be that way. With a modest investment and course correction,
I believe Apple could pretty easily become the dominant force in desktop computing. I can't understand why they seem to have no interest in doing that, but oh well.
