I'm a happy long term Mac user. However, I've resisted buying first generation products, and I wouldn't buy Apple products without an option to cancel the purchase. I'm happy with the attention put into the product design, but not with their quality control. If Lenovo made laptops with touchpads that worked as well as MacBooks, I would switch. But no such luck so far.
The Thinkpad X1 Carbon has a nice touchpad with 2-finger scroll as well. The only (minor) quibble I have with it is that it only lets you go one direction with the 2-finger scroll (you have to swipe down for down--you can't reverse it like you can on a Mac.) Otherwise, it's very comparable.
