The correlation to Cook taking over is pretty crazy, particularly with the all-in-ones. For the laptops, you can see it's more of a step up, then plateau for a little bit, before the next step up, with each plateau more or less being longer than the last one. It's probably mostly a coincidence, but Cook's pragmatic approach to thins is likely a factor.
I honestly honestly feel like Apple needs to do one of two things: they need to raise the base ram up to at least 10-12 GB, or—because truly not everyone does need more than 8GB (though, I would argue more people would do better with more, even if they don't realize it)—lower the price of upgrading memory. There's absolutely no way memories is costing that much, there's no justification beyond them price gouging for profits. I would feel much happier with them as a company if they kept the base ram at 8 GB, but made the upgrade to 12 or 16, and so on, a much smaller price jump.
