Though I'm not familiar with the Lenovo trackpads in particular beyond playing with them on display models, the trackpad on MacBooks is a huge differentiator over any of the ones I've had on PC laptops. It works so well you forget how well it's working until you start using a different computer with a trackpad that now feels completely broken.
It's honestly one of the reasons I'm still contemplating getting a new Mac when it's time to upgrade. I've never seen a PC laptop with both a comfortable, large, smooth trackpad and good drivers that provide the kind of scrolling you get with a Mac.
