It does sound like you might be better off cutting your losses and selling the 14” MBP and getting a Mac Studio if that is remotely feasible for you to do. Can you live without a mobile Mac and just use an iPad in combo with the Mac Studio?I'll probably step on some toes with this but I hate working on laptops, even my 14" MBP. The thing is permanently plugged in to an external display with a BT keyboard and mouse. It got to the point the other day that it noticed I rarely use it as a laptop and started charging the battery to 80% so I don't ruin it.
What kills the laptop?
1. Awful working position.
2. The thing still has sharp edges at the front. I look like an emo who has been slashing their wrists after a few hours
3. WiFi. I hate WiFi. I really would rather have ethernet.
4. Batteries. They don't last forever and then you have to pay lots of money to replace them.
5. Far far far more fragile than desktops.
6. Power and USB-C connectors wear out as you move them around all the time.
Really I should have bought the bottom end Mac Studio or cheaping it, a 24" iMac. But the Mac Studio didn't exist when I bought the MBP and the 24" iMac had a lead time as it'd be a custom build.
If I am doing anything mobile I prefer to use my iPad if I'm honest.
