The peson was trying to compare a tv comparison to an Apple/non-Apple comparison. I stand firmly by my contention that that is not a good comparison because Apple products are in a class essentially by themselves (not even approached by Sony TVs). The illustration is weak at best.
The illustration is even more non-sensical since it specifies a top-of-the-line Mac with a bottom of the line no-name.
Wow. You're either being intentionally obtuse or you have no hope of understanding this. But we'll go through it one more time.
A second-hand Sony television is often higher quality than a brand-new generic manufacturer's TV. In the same vein, a second-hand Macintosh is often higher quality than a brand-new generic manufacturer's computer.
Nobody cares how highly you rank Apple. Their specific quality is irrelevant to the comparison.
