I switched relatively late (2011 or so) after about a decade of Windows and Linux laptops. The actually-usable trackpad that didn't make me want to carry a mouse everywhere if I actually wanted to use the computer on the go, the battery life that didn't have me looking for outlets everywhere and carting my power supply all over the place, the screen quality, and all the hardware actually working the way it was supposed to (including all sleep modes, with no fiddling and crashes- or hangs-on-wake pretty much never happening!) were all like entering a new world. "You mean I can just close the lid, unplug, and walk away, without taking other stuff and without babying the sleep process? What is this madness?"
