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.
Yeah, I've got the last of the all silver MacBook Pros before they went to the buttonless pad and black keys. The buttonless pad is hard to get used to.
