I can't read the article because the site is hosed. I have a Lenovo ThinkPad X1 Extreme, and the touchpad is as good as any MacBook I've ever owned. It's the only non-MacBook that I've encountered where the touchpad is even usable.
I don't usually run Linux on it, but I have, and I don't recall it behaving any differently than it does in Windows. Maybe the pinch gesture doesn't work in Linux; I'm not going to reboot to test.
