My PC, however, has components that are oh, 10 years old? Sure, it has a 1-year old motherboard, CPU, 3 year old RAM, a 2 year old GPU, and a mix of SSDs and HDDs, but the case I bought in 2006, as with my MX518 mouse.
This kind of longevity of components is good for us. Throwing out your appliance every 5 years because Apple decided to solder RAM instead of sacrifice 1mm of thinness and provide a slot is good for Apple, and Apple alone.
There's one single screw that sets the trackpad's click sensitivity. I loosened the click even during the warranty period because it was too strong (and loud) for my taste. A tiny bit of rotation and ideally loctite to fix it.
(Incidentally, when I last went to buy a replacement battery from an Apple Store, they wouldn't let me install it myself even though the polycarbonate MacBooks had user replaceable batteries. They insisted I bring in my MacBook and leave it with them overnight to have a Genius install it. I ended up cancelling it and getting a NewerTech battery replacement, which is both cheaper & has better battery life than the Apple model.)
So yeah, it doesn't look great when Apple says "replace your 5 year old computer" but as a whole, they do a great job of making products that last. Also, news flash, they are in the business of making money.
