then you'll most likely keep it for a few more years after you do the SSD install. It'll feel like a brand new laptop once you put it in. If I was you I'd put the SSD in and wait for your software/plugins to be compatible with the new Macs before buying.

I tried to hold on to my MBP 2012 for as long as I could since it's basically impossible to swap out parts on the newer ones, but the battery life is horrible on it. You only get 3 hours on a brand new MBP battery. I'm eventually gonna have to get a new Macbook and have to deal with all the bullshit that comes with them.

For now I've been using a Lenovo with Linux on it. That shit gets 8 hours of battery life. I haven't turned my Mac on since the pandemic started.
