I think the main thing is it’s really rare to just have one project in the works anymore. So you buy the 5day turn and work on something else in the interim. If somehow you really blew it in the project planning stage, and you simply must have it now, then I guess it’s kinda a toss up. In those emergencies rarely does cost matter but definitely your geographic location will limit options.

Do fuses count as an electronic component or does it have to be an active device? If so then I can name a couple. :)

I wonder why Apple would even want to protect a battery charger IC? All of the interesting stuff would be in software anyway. Maybe the reason repair shops can’t buy it is more mundane. Basically it’s an expensive part, particularly to Apple’s logic board, and distributors don’t believe there are enough Rossmanns out there to sell through a 100k part factory order. When I made PCBs for a large company I had parts I could buy direct from Maxim, at 250k parts minimum, that weren’t on Digi-Key for just that reason.

You can actually see this for yourself in the new open source PDKs.

See how there are six foundry provided cell libraries that make different performance, power and area trade-offs. Even though it’s all 130nm.

There are even more libraries than that too. Like the OSU one that makes even different trade offs.

I was using us to mean all customers in Apple Store.

The stories from winter when there was unionization talk were horrific.

I don’t know, but if it were me being subjected to that, all customers would likely start looking the same and I’d probably not be sympathetic to giving them the benefit of the doubt. I definitely could be wrong but I suspect there are a lot of tired retail workers out there.

There are trade-off there to consider.

One get's ruggedness but carbon fiber is generally not a good thermal conductor which could be a problem for a laptop with no fans. And titanium is very expensive compared to aluminum.

Like all engineering. It's about priorities.

Filed in Sept 2021.

"A class-action lawsuit is being planned on behalf of M1 MacBook owners who say that screen cracks were occurring during normal use, with both the M1 MacBook Air and M1 MacBook Pro affected.

Apple has mostly claimed that the cracks are the result of accidental damage, including in the case of the 9to5Mac reader who first contacted us"

“It will be the world's largest magnetic confinement plasma physics experiment and the largest experimental tokamak nuclear fusion reactor.”

Does the $3.9B spent on ITER not count?

I’m super happy to see these things, and some money is better than no money, but judging by how much my lab spends per year, $50M/yr isn’t going to get them very far. And we do consumer electronics.

> How should they know where they want to go if they're entry-level?

I think it’s totally reasonable to expect people to have a plan. It’s also totally reasonable, and expected really, for that plan to change over time. But working without a plan, which implies working without goals, is rarely a recipe for success.
