>So only ~35 million people?

Citing large absolute numbers for rhetorical effect is dishonest because multiplying a huge number with any percentage will result in a shockingly large number. The original claim is that "people who keep computers from 2009 to play with and wish they could get more use out of their 12 year old iPad Air [...] it's simply not a thing for most people", which is true even, if there are millions in absolute terms.
