Of course, anyone who already owns a MacBook Pro quality monitor, trackpad (not mouse, the MacBook Pro includes a trackpad), quality audio/speaker system, and Apple keyboard will save cash on a Mini purchase as opposed to a MacBook Pro, as they've already paid for that stuff.Okay, but let's take other people's situations. Namely me, as I am buying an M4 Mac Mini soon.
Let's go apples to apples: M4 Mac Mini 16/512: $799 vs. M3 Macbook Pro 16/512: $1599 so 50%
Then factor in keyboard (MS Sculpt from years ago still works) for work and gaming: $0
Mouse: Logitech G502 Lightspeed Wireless (already own): $0
Don't use trackpads so no loss there:
Monitor: LG 4k Standard IPS 27" which I already own: $0
So.....there ya go. A literal 50% savings since all I need is the mac mini.
But on a like-for-like comparison, which I did, there is pretty much zero saving for a new Mini purchase if you haven't purchased all the peripherals beforehand.
"since all I need is the mac mini."
Bingo, you're getting a good deal. I considered the Mini too, since I'd be upgrading from an M1 and already have that stuff too, but since I now need to be mobile, the MBP is the most likely option instead.
