To be fair, Apple popularized the buttonless trackpad trend and is reasonably good at executing it; originally I was skeptical of it but Apple's clicky trackpads are very nice to use.

That said, Lenovo made the decision to integrate a Synaptics Clickpad in a lot of the recent ThinkPads and it's basically untenable - on my ThinkPad I've turned the trackpad entirely off because the Clickpad is just so unusable.
