THanks! i could get by with this mac mini. but im getting more and more paid projects and i need to be portable sometimes and need my projects with me. when i know im going to be away from home for hours and need my projects, i use my 2018 13 inch macbook pro but its slower than Mac mini but most importantly its a super pain to deal with two computers, some plugins only allow 1 activation at a time, preferences and plugins and presets upto date on two computers, two back ups, its just a pain. so thats why i want to upgrade also move to just using one computer that can do everything. and the latest project i did basically pays for the macbook pro i want to get so it makes sense kind of ( also want to treat myself lol)
P.S. also my mac mini and older macbook pro both have 256gb internal memory and i want to finally stop having external drive hanging off all the time, so 1TB internal on next macbook is another reason
Okay in this case it may be a good time to jump into and invest in a 16" then:
1) The Apple Silicon transition just happened and it leap forged the Intel generation of Macs (which you know 1st hand, with your mini)
2) The following iterations of M2 on wards probably won't see a change as significant
3) The 14" 16" MBP just received a drastic form factor change that is almost universally regarded as huge improvements (except the notch), again this chassis will carry on for another 2-3 iterations
4) If portability is a huge consideration then you are looking at 14/16" MBP vs 13"MBP vs Air, where the latter 2 are subjected to renew any time within this year
So buying a 16" is a really sound investment at this point in time.
Then as to configs; you have budget concerns, don't get anything more than you absolutely need:
1) 16" is indeed a substantially larger real estate than 14", and it only cost 200 more
2) 1TB over 512GB ask price is reasonable, and you need that space as a long term main machine
3) 32GB RAM has questionable need for your case if not clearly useless
So the mid-tier 16" M1 Pro 16GB 1TB is your sweetspot. It is a standard config so it is easier to score deals on 3rd party store or Apple's official refurb. Wait time is also a lot less than any 32GB BTO for instance.
The only way you can save even more is to config a custom 14" from the very base with the binned chip, but only add 1TB option.
