Go on, I’ll bite: why?
If a desktop is fine then yes you can build some great Windows rigs for much less money.
And here’s another kicker—all those “comparable” Wintel laptops viciously throttle their performance the second you unplug them from the wall. Not the MacBooks. They keep being just as performant on battery as they do plugged in, while still delivering that excellent battery life. It’s remarkable.
I really can’t in good conscience recommend anything but a MacBook to a prospective laptop buyer right now, unless the user requires specific software that only runs on Windows. Save a couple hundred bucks only to end up with a vastly inferior machine? It just doesn’t make sense.
