Go into a non-Apple space though, where money is not "no object," and see how many people would choose a 16-17" 1920x1080 screen over a 13" MacBook Neo purely because of the big screen, nevermind that the Mac has roughly 4x the number of pixels. I guarantee you, it's more than you think.
My only point was that yes, the MacBook Neo wins on quality construction and aesthetics (but I'll argue NOT on durability since plastic laptops can take a lot more incidental bumps than Macs will), cool factor/perceived eliteness, and screen quality. I am sure there are plenty of people who care about those things, but I think most of those people are already buying a Mac today.
I suspect we'll actually see a modest cannibalization of those casual but cheap Mac users from the MacBook Air, since most people don't really understand how to evaluate RAM and storage size, but a lot of them will have a bad experience after filling the disk.
