Dual-Pixel sensor in the Google Pixel 2... does iPhone have this? Does it matter?

No, they don't. Ultimately both phones produce the same results though, great pictures.

What situations would qualify under the "auto focus" not being fast enough? Is this typically low light shots like trying to focus on the moon? Or of there is some fast moving target like a cheetah running?

I like how fs454 mentioned how dual pixel means smaller pixels for each shot, even though you get "more detail", the pixels are degraded, so that in and of itself seems like a compromise to me besides cost. What it sounds like is low-light performance should be better on the iPhone 8+, or any other phones with non-dual pixel because more light gets to the "bigger pixels" (if this is the right way to think about it, unless there is some major compensation that dual-pixel technology uses to deal with that sort of situation).

Though it seems a little bothersome that Nikon also has a patent for Dual Pixel Auto Focus:

So if Canon and Nikon both have this, and no one is complaining about their pixel size not letting more light in, is this because DSLRs already have big image sensors, so they can afford to offer dual pixel autofocus without compromise to image quality... while smartphone sensors are already much smaller, so dual pixel does not offer as big of an advantage, and in some cases (like Samsung's or Google Pixel 2's case) photos might turn out worse than the iPhone 8+ because of it?

the iPhone 8 is already not as good in low light as the note 8. so i bet the pixel 2 will blow way past it. Dual pixels or not.

The iPhone 8 is very close to the Note 8 in terms of low light photography. The Note's main advantage is the larger sensor, but Apple's hardware noise reduction and software is really excellent this year, given that the iPhone is using a very similar sensor to last year.

The detail in low light is not even close

how different is the focus time between the cameras?

iPhone has 2 camera's which means it has twice the pixel count for things where google uses this 'dual pixel' technology. So yes Apple does have this and it's even better because it's using full pixels.
