5 Prevalent Themes

Theme	Summary & Supporting Quote
1. Mac Pro discontinuation & missing upgrade path	“They’ve been trying to kill the Mac Pro for over a decade. I wonder how long before they backtrack again? It seems like they should at least have a migration path for users who needed the expansion cards the Mac Pro supported.” – al_borland
2. Expansion‑card justification falls apart	“It would seem like they could decouple it and sell a box that pro users could load cards into (like other companies do for eGPUs). It wouldn’t feel like a very Apple‑like setup, but it would function and allow Apple to focus where they want to focus without simply leaving those users behind.” – al_borland
3. Decisions driven by inventory, not user needs	“A bunch of the Mac Pro decisions seem to have been more driven by ‘we have a warehouse of these parts’ than ‘this is what the system needs’.” – bigyabai
4. Apple’s focus has shifted to consumer profit	“The money’s all in selling phones to teen girls now, and taking their mafia cut of app store sales.” – longislandguido
5. Future of Apple‑Silicon workstations hinges on model shrink	“Apple is counting on something else: model shrink.” – wpm
