Vlad Savov, writing for The Verge, takes PC manufacturers to task:
There’s no denying that the world of personal computing is changing, and most of our interactions with technology and the rest of the world will be happening on more convenient mobile devices. IDC reports that 337 million smartphones were shipped in the second quarter of this year, dwarfing the 66 million PCs shipped in the same period. Neither Microsoft nor Dell can do much to reverse that trend. But while PC sales keep dropping, Apple’s Mac division has kept steady and even grown over the years. This is underpinned by the halo effect of the iPhone’s ecosystem, though the more prosaic reason is that MacBooks are just plain better, and two of the crucial factors in this are the quality of its touchpads and longevity of its batteries.
For as long as I can remember, touchpads from all of the PC OEMs have been absolute crap compared to Apple's. Just terrible. They've had more than a decade to get it right, and have nothing to show for it.
What's interesting is that so many people buy laptops without much regard for the quality of the touchpad. It's the primary way they're going to be interacting with this expensive gadget, and it can never be upgraded, but it's an afterthought for most consumers.
It's like buying a car with a tiny steering wheel made of cheap plastic that locks up mid-turn and a gas pedal that takes two or three pumps to respond.
