My daily driver is a Dell XPS running Pop and frankly it’s simply not as good.

Astronaut 2: Always were...
Industrial design in the computer industry has been chasing Apple's taillights since forever ago, laptops especially so. Look at 90s laptops: almost all of the tropes associated with a 90s laptop, including the trackpad front and center with the case forming "armrests" on either side, were introduced with Apple's PowerBook series. When Apple showed with the first MacBook Air how thin and light a full-sized laptop could be, Intel countered with "Ultrabooks". And on and on. Basically if you get a laptop, you're either buying Apple or an Apple ripoff. Even Lenovo have incorporated Apple-isms into ThinkPads (mainly the keyboard and thinness).
