Honestly, I always purchase Applecare with any machine I purchase from Apple, just because everything is soldered into place and not user serviceable, meaning if something does go wrong you're looking at a very expensive fix!
A previous MBP16" I used to have had a port that kept randomly disconnecting anything connected to it a few years back. Took it in and they ended up replacing the entire mainboard - and this was literally a month before the 3 year Applecare was due to end!
Otherwise I've rarely used Applecare for a computer/laptop, but I know the one time I don't get it something is bound to happen!!! lol
Same with my iPhone. Always get it, never used it - until last year when my phone was snatched from my hand and stolen. Thankfully covered by Applecare and replaced within 2 days.
I'm waiting for the M4 Max Studio, and I will certainly get the Applecare coverage with it......for me its more piece of mind than anything else......
