It's hard to replicate the R&D that went into Apple's trackpads. I don't know this for sure, but I suspect that most laptop companies do not actually engineer their hardware as much as cobble together existing hardware. Even among those that do engineer their hardware, they don't pay as close attention as Apple. (Also they might not engineer on a low enough level in the first place)

There are some haptic trackpads popping up that are okay.
