The guy in the linked video up thread tore the whole computer down in 6 minutes. I'm pretty sure most people can manage to find 12 minutes out of their life every 5 years to replace the battery if they want. But if that is too arduous, you can pay Apple to do it for you for a mere $149, with the battery included in that price. Given that a comparable battery from iFixit will cost you $80-$100, that's just ~$50 to have someone save you the hassle of having to remove 18 screws from your laptop every 5 years.
I'll take it over the plastic pieces of garbage that flex and bend and creek, and feel like they were taped together by a 6 year old, which is most other PC laptops in this price range.
This is part of what's plagued the PC laptop industry for decades: Obsession with specs and measurements and geekbenches and similar things, over "does this feel like a cracker jack toy?" and "will the hinge break if I open the lid?"
Apple’s official illustrated guide shows you only need to pop the 8 case screws, 2 screws holding down the battery connector, then route the cables away and remove the 18 battery screws.
I mean, yes, it is easy. No adhesive and just a couple of clips on the case. You could replace the battery in 20 minutes with little anxiety that you're going to cause damage getting to it.
As it turns out, once battery life hits a certain baseline, people prefer devices where the battery is harder to replace but larger over devices where the battery is hot-swappable but smaller.
