I'm in the same boat with the exact same MBP. I bought a new 2015 MBP - they were still making and selling them in 2017 when I got it - and skipped the 2016-2019 models for all of 'those' reasons. With the new MBP 14" (or 16") as everyone has noted, it may be the perfect upgrade for the now 'classic' 2015, and everything I could want. If I felt comfortable spending the funds I would have already done the deed. But, I really don't need it. The 2015 MBP is still the same computer that I bought it for; great display and keyboard, ports, [mostly] fast enough for my work, and form factor. The 2021 MBP would be a total upgrade in every way, and I'll do it in time (sooner or later), but for now, I've double-downed and recently bought an old Thunderbolt Display (boxed, like new, and a couple of hundred dollars) that pairs perfectly with the 2015 MBP Thunderbolt 2 port and MagSafe charging and gives me something shiny bright and new [to me] for photography/video viewing and editing. I've resigned myself to living in the digital past for the time being. I guess I'm just not desperate and can wait till it is really necessary. The mini-LED would be nice, and the M1 processing power, the 'new' factor, are the reasons, and I am not at the point the cost of upgrading tips the scale to make the switch. If you have decided yourself that it's time, do check the APPLE refurbished store. They have computers available for purchase now and save on the cost of what is a like-new computer.
