Am I dumb? Is it dumb to get an older MacBook compared to a newer one? Please help
I prefer the 2015 MBP too, and I love older Macs.
But, what would you do with it?
To better answer you question, we would need to know what you plan on doing with it and what the specs of the 2015 MBP you would get.
My family uses a lot of older Macs.
Here are the current Macs that are used daily at my home, listed from most used to least:
-Late 2012 27" iMac, BTO with i7 and 2GB 680MX, I installed some RAM for a total of 24GB.*used my me
-Late 2006 Mac Pro 1,1, upgraded over the years many times. It is still really fast. *used as a PLEX server
-Mid-2011 27" iMac, Maxed out BTO, A friend found this in the trash and gave it to me to fix.*used by my children, a side note, this iMac goes for $700-$800 on ebay, and I fixed it with a SSD and baking the GPU.
-Late 2012 17"MBP, Given to be my my brother when it stopped working and I fixed i.t*used by my children
-Mid 2012 11" MBA, Can't remember the specs, purchased a week before the 2013s came out.*used by my wife
These are all Macs that are used daily. To be fair, many of them had the best BTO options and/or were upgraded over the years, but still, they are awesome computers.
While I think all of them are pretty fast for their age, I do most of the heavy tasks using my Late 2012 iMac, mostly video encodes.
I don't have plans on getting a new Mac unless my main Mac dies or maybe when the 2019 Mac Pros show up on the refurbished stores.
I think if you got a 2015 MBP for basic usage, you will be good for many years to come.
