I guess people really just have wildly different feelings. I think Apple's laptops are terrible. Hot, poor keyboard, hard trackpad - you've gotta really press down on the thing. Maybe I'm "using it wrong". (Excellent screens though.)
I think I've had trackpoint buttons fail once, sorta. On a used ThinkPad X201 I got for $300, and just this week, clicks seem intermittent. But it's been under heavy use in an elementary classroom so I'm not sure what kind of stress it's gone through. I've never had an issue with laptop buttos otherwise that I can recall, thinking back to the early 90s.
