If you’re heavily invested in Apple apps (iMessage/Calendar/Reminders/Notes), you need a Mac to give the agent tools to interact with these apps. I think that combined with the form factor, price, and power consumption, makes it an ideal candidate.
If you’re heavily invested in Windows, then you’d probably go for a small x86 PC.
Can you imagine giving an AI access to your messages, notes and calendar though?
I use agentic coding, this is next level madness.
Some of those connectors are only available on the mac and some only on the iPhone. Like notes is available on the mac, but not on the phone. Vice versa for reminders.
