I'm gonna wager a guess that the Sony "Viao" X505 didn't have an SSD, for one. But ignoring that for a second, the Ultrabooks literally *are* copies of the MacBook Air. We're not just talking about the concept of a super small laptop, which Sony obviously did years ago, we're talking about computers that almost visually-identical clones of the Air. So, no, the X505 looks nothing like the Air, except that it's small and that's it's a laptop.
Instead of farting out the word, "fanbois" any chance you have, how about you actually read what used2win32 said — "Do an image search for "macbook air" and look at the pics. Then do one for "ultrabook" and compare the images." God, you're an idiot.
