surprised by your experience with an older laptop. I have both a 4 years old dell (forget it's name right now, for biz uses) and a 2015 MBA (which makes it 6 years old now), and they are both getting SLOW. In a vacuum - they are fine, they pull through. but they are notably slow machines. (i prefer windows but can't stand the dell and find myself keep going back to the mba - although youtube sucks on that machine with chrome)
edit: oh the mba battery is still a miracle compared to the dell's, btw
can't tell u how many times I asked American construction workers/contractors about this, and none knew the answer. Glad to finally have an answer. thx.
Site note: can't stand the amount of noise(!) going throw the house as opposed to concrete.
