You'll be glad you did. I loved my 2015 MBP. I even drove 3 hours to the nearest Best Buy to snag one. That display was glorious. A fantastic machine. I eventually gave it to my sister, who continued using it until a few years ago. The battery was gone, but it still worked great.

When you upgrade, prepare to be astonished.

The performance improvement is difficult to convey. It's akin to traveling by horse and buggy. And then hopping into a modern jetliner, flying first class.

It's not just speed. Display quality, build quality, sound quality, keyboard quality, trackpad, ports, etc., have all improved considerably.

The performance jump between a top-of-the-line intel MBP (I don't remember the year, probably 2019) and the m1 max I got to replace it.. was rather like the perf jump between spinning disks and SSDs.

When I migrated all my laptops to SSDs (lenovos at the time, so it was drop-dead simple), I thought to myself, "this is a once-in-a-generation feeling". I didn't think I would ever be impressed by a laptop's speed ever again. It was nice to be wrong.

A family 2018 Macbook Air got a second life with a battery replacement. Cheap kit from Amazon, screwdrivers included, extremely easy to do. Still in use, no problems.
