Earlier quoted context omitted.
So it’s disingenuous to claim “similar performance” by arbitrarily removing metrics from the mix.
On the contrary, it's disingenuous to act like resolution or color are metrics of "performance" when the colloquial usage of the word generally refers to processing speed and memory capacity. I/O speed would qualify, but is only one metric; it is correct to say it is outperformed by other machines at lower price points when accounting for the CPU and RAM.
The ""colloquial usage of the word"" very much includes I/O performance; disk speed has historically been the worst bottleneck, aside from network access.
Resolution also affects performance: it's how much information you can view at a time.
Most cheaper laptops do not present the same value as a MacBook Pro unless you ignore some of the advantages of the MBP you’re comparing against.
