my dad has a 2018 and he's had it for like 6 months iirc, and his is still working just fine. he only uses it occasionaly so it's no surprise to me, like it might get one or 2 hours of use in total a week.

I was typing a history essay outside once. That's when mine had issues the first time. 

@floofer i do that constantly around my laptop (2012 MBP) and mine is totally fine. a keyboard shouldn't fail because of some bits of dust or food... 

@floofer that's fine, but i'm the sort of person who uses a computer for as long as i can. either until it stops recieving updates, stops working or becomes too slow. my current machine is almost 8 years old and i have no intention at this time of replacing it. warranty wouldn't work for me because i'd want to use that laptop long after the warranty runs out. 

I'm like twilight. my current laptop is from 2014 and my desktop that kicked the bucket was 2008.
