A:Answer Pretty much like most newer trackpads...no actual buttons. There's a division line at the bottom and the lower portion of the trackpad basically "flexes" to provide left and right click. If you're used to the tactile feel of buttons to click without looking, it'll take a day or two to get used. However, it becomes natural and you don't need to press any harder than a normal trackpad to click.
As for "feel" of the surface, it's a little more textured than what I'm used to. Usually, the trackpad is smoother than the rest of the case material. This one is only slightly less textured than the case...and to me feels like I'm sliding on case plastic many times. But, again, nothing that you can't get used to.
Overall, sensitivity and behavior is just like any other pad...just "feels" a little different tactile wise.
