Some of my M1 MBP Max keys are losing their coating, and the battery is at 74% capacity. At some point soon I'll need a service. But other than that, I have no real complaints. Even the case edge where my arms constantly rest doesn't look too bad.

My next MBP will have 128GB memory, but these prices just wanna make me wait longer.

If you don't mind a bit of DIY, apple runs self service repair.

Those keys are easily replaced, my friend.
