At my "Genius" Bar appointment today, I couldn't help but eavesdrop on the appointment 2 ft away from me since I had the same issue until a couple days ago. I'm glad my guy was helpful (and hot): They were talking about the SMS on his 13'', not sure if it was 2010 or 2011. The customer was complaining that his computer was too loud and asked why it's more sensitive. Apply guy, "Well that's part of the reason why Apple is pushing towards calling them 'Notebooks' now and not 'Laptops,' because Apple's design is requiring more and more that they're used on a flat, hard surface and not on your lap... blah, blah..." While what he said may be true, I don't think that was the answer the guy was looking for. I think we all bought ''Notebooks'' because we plan to carry them around and probably set them on our laps from time to time. Since they're "notebooks", can I toss it on my desk or sit on it?
