Because realistically in the laptop computer space Apple is obliterating everything else right now.
You can usually name a laptop that has some feature better than a macbook, but the overall package is so strong in so many avenues. Sound quality, screen quality (even without leaning on fancy new tech like OLED), trackpad quality.
Would you rather they target the Dell Latitude (Coil Whine, crazy power-off issues caused by C-States, poor thermals) or Thinkpad T-series (USB-C port stops charging and requires motherboard replacement, thermal issues, weak speakers, also coil whine, unstable radio) or HP’s elitebook (randomly doesn’t wake from suspend, hinge cracking and keycaps falling off even with light wear).
The other SKU’s are a race to the bottom, despite being more expensive for the base-system (which I find ironic).
It’s a poor north star to take a degrading product line as inspiration.
