Everyone who has ever had to work in IT cares. When you need 81 screws to replace a motherboard (as a previous example cited) you wind up spending a magnitude of time longer fiddling with a laptop just to fix it. Multiply that times 100 and you have long support times and disgruntled workers.
The attitude that a laptop has to have eighty billion screws to be well-engineered is nonsense. Thinkpads are the perfect example -- they are known for being extremely sturdy and tough, but also have a reputation for being remarkably easy to work with in terms of parts replacement, etc. Defending Apple for "wanting to make sure it works perfectly" does not hold water -- we may as well admit that they don't really want _you_ poking around in your own computer under any circumstances.
