> M4 makes the new iPad Pro an outrageously powerful device for artificial intelligence. Isn’t there a ToS prohibition about “custom coding” in iOS? Like, the only way you can ever use that hardware directly is for developers who go through Apple Developer Program, which last time I heard was bitter lemon? Tell me if I’m wrong.

Well, this is the heart of the "appliance" model. iPads are appliances. You wouldn't ask about running custom code on your toaster or your blender, so you shouldn't ask about that for your iPad. Also all the common reasons apply: Security and Privacy, Quality Control, Platform Stability and Compatibility, and Integrated User Experience. All of these things are harmed when you are allowed to run custom coding.

(disclaimer: My personal opinion is that the "appliance" model is absurd, but I've tried to steel-man the case for it)

The 256gb and 512gb models have 8gb of ram. The 1tb and 2tb models have 16gb. Not a fan of tying ram to storage. https://www.apple.com/ipad-pro/specs/

The economic reasoning behind this doesn't make sense to me. What do they lose by allowing slightly more freedom in configurations?

It forces you to buy multiple upgrades instead of just the one you need.

I always wonder how constraining it is to design these chips subject to thermal and energy limitations. I paid a lot of money for my hardware and I want it to go as fast as possible. I don't want my fans to be quiet, and I don't want my battery life to be 30 minutes longer, if it means I get more raw performance in return. But instead, Apple's engineers have unilaterally decided to handicap their own processors for no real good reason.

Given that recent Apple laptops already have solid all-day battery life, with such a big performance per watt improvement, I wonder if they'll end up reducing how much battery any laptops ship with to make them lighter.

Call me crazy, but I want all that power in a 7" tablet. I like 7" tablets most because they feel less clunky to carry around and take with you. Same with 13" laptops, I'm willing to sacrifice on screen real estate for saving myself from the back pain of carrying a 15" or larger laptop. Some of this is insanely impressive. I wonder how big the OS ROM (or whatever) is with all these models. For context, even if the en…

Aren't phones getting close to 7" now? The iPhone pro is 6.2", right?

"With these improvements to the CPU and GPU, M4 maintains Apple silicon’s industry-leading performance per watt. M4 can deliver the same performance as M2 using just half the power. And compared with the latest PC chip in a thin and light laptop, M4 can deliver the same performance using just a fourth of the power." That's an incredible improvement in just a few years. I wonder how much of that is Apple engineering a…

> I wonder how much of that is Apple engineering and how much is TSMC improving their 3nm process.

I think Apple's design choices had a huge impact on the M1's performance but from there on out I think it's mostly due to TSMC.

I think it’s a price discrimination technique.
