Again, we’re not comparing a brand new Mac price to an old PC price. Yes, old will be cheaper. Old MacBooks are cheaper than new ones, too.
But for giggles, let’s look at the old PC.
Despite being heavier, wider, taller, thicker, slower, dimmer, lower resolution, hotter, older, and having less battery life, it is, indeed, $20 cheaper.
Put another way, there’s no way on earth I’d pick that over a MacBook Neo to save $20 at the cost of having a worse laptop in almost every way.
