Naaah. Warranty extension ll be expensive
Naaah. Warranty extension ll be expensive
I've been using apple laptops exclusively since 2004. Not once have I needed warranty. My current machine is 2014 MacBook Pro which I bought second hand in 2015 from eBay. Still works great.
I don't think other high end windows laptops need warranty extension either. If it didn't break in the first year (assuming some manufacturing defect), chances are that it wont break in next 2 years either.
Just make sure your laptop doesn't get hot too much and you should be fine. Considering M1 is really good at managing heat, a warranty wont be worth it IMHO.
