On the light bulb thing, with the older incandescent light bulbs, I'm sure the early ones were probably designed to last a long time. At the time, he
wasn't building them to sell them. He was trying to prove a point.
At any rate, the incandescent bulbs we use (or did before the CFLs started taking over) were probably not made as well but they were much brighter,
they're cheap (so if they burn out it doesn't cost much to replace one) and the way we use them is hard on them. Turning them on and off all the
time might save electricity but it's hard on the filament. It's the way they work. They are constantly degrading but a bulb that has a lot of age on
it is much more likely to die when you first turn it on. That's when it has the highest stress on it. A bulb that stays on constantly will probably
last much longer. Maybe not as long as the Edison bulb but it will almost certainly outlive one that's turned on and off all the time.
The laptop? They're just not designed to last. You notice because they're expensive. If you could replace it for a few dollars, who would care?
Engineers don't care about durability. They don't have to pay for a new one when it dies. And further, their job security depends on keeping people
buying a new one every couple of years.
I never bought a laptop in my life because I don't need one. I hardly ever go anywhere. If you just sit in one place all the time, a laptop is a
piece of junk compared to a desktop. Plus, with a desktop, you can build your own. You can build it to last ten years if you really want to. The
laptop is a specialized product. You have to buy one that's already been designed a certain way and made the way they want to make it. You can't
overbuild your laptop. You might be able to take it apart and install a beefier cooling solution if you're brave and good at that kind of thing but
they generally don't make them easy to work on.
If you look at Youtube vids where people take them apart, you can see just how chintzy the fans are in most of them. It's a wonder they work as long
as they do. Size constraints are an issue but they could probably do better if they wanted to. People who rely on laptops tend to be the kind of
people who will just go buy a new one when it starts to sound like a helicopter. As usual, the market is driven by necessity. If the manufacturer
doesn't have to build a laptop that'll last 5 years or more, why would they?
