Are you referring to the new ones without buttons?
Actually no, I hadn't thought about that. I'm still using an older one with the one big button. I didn't like the button-less ones at first either but after fooling with it at Best Buy I think you could get used to it easily enough. Essentially I just pretended the button was still there (I tend to click with my thumb). Felt natural enough for a 5-minute store demo. I'm sure I'd get used to it with time.
