Net result: iPad (4th-gen) has 4 times the number of pixels that the iPad 2 has.
The "2x" resolution (264 ppi vs. 132 ppi) describes the linear resolution of the screen, not the surface area per pixel.

As shaky as AI writing often is, I really don't see this particular thing as a problem to a reasonable degree. They didn't specify linear or area dimension, so it's not necessarily wrong. The dimensioning on the images should be enough to infer that they mean linear dimensions. Pixels are almost never specified by area anyway, they're far more often measured by pitch, these days more often specified as pixels per inch, both linear dimension.

I test drove a BMW 330 and an M5. The M5 was noticeably faster, but is larger and harder to park in confined spaces.

 

The 330, while slower than the M5, was still VERY quick, certainly faster than competing cars in that category. The reduced size makes it a better choice for my high-density urban situation needs, so I'm willing to accept merely "excellent" performance as opposed to "ridiculously good."
