Base Pro for me.
Struggled for a while being new to Apple but once I got to grips with things it was a no-brainer.
Looked long and hard at Mac Mini, but the Pro is both a Macbook and a Mac Mini (admittedly with fewer ports but an adapter sorted that out) so once I'd figured it out that way it was simple, the Pro is both.
I've also an external monitor, magic mouse, and magic keyboard coming today, so my Macbook will also form the basis of a desktop set-up, which I haven't had for a few years, and if I'm happy enough with the Apple life the next move will probably be the next variant of Mac Mini to make the desktop set-up more permanent.
So that's why I went with the base Pro, foregoing a RAM and storage upgrade which I may not even need has bought me a mouse, keyboard, and monitor, and if it get to the stage that the Pro is lacking a wee bit, then that'll be the time for an upgraded Mini which will use the peripherals I've bought instead and the Pro will still be well capable of laptop duties for many years to come.
Also, it'll be used outside a bit (for scanning sheep as it happens!) and the extra screen brightness will be very desirable.
Also, I shouldn't need an external mic.
Also, external speakers are supposed to be better.
Also, extra battery life may be useful, see sheep scanning point.
Also, from what I've seen of the touchbar so far, I think I might like it.
Also, first Apple product so wanted to give it a decent chance.
Looking forward to getting it now.
