I can understand the OP's thinking, although I have Lenovo's Yoga 2 Pro.

With my laptop in my lap, I typically have to be leaning back to comfortably use the keyboard. Sitting up or slightly leaning forward, it's more comfortable to grasp and scroll with the screen itself, maybe bent a little further back than typical usage. It's a more comfortable resting position.

Although sometimes I just flip my yoga into a tablet and that's just swell

Many times touch is more convenient than the trackpad especially when I am feeling lazy. I am reading this thread on a Y2P, lying on my side, laptop on the bed, one hand supporting my head and the other scrolling the page on the screen. Much easier than any other method.
