Quite a bit disingenious, aren't you?
The Mac Air from 4 years ago is "old" technology, while the ultrabooks contain the latest in technology from Intel and other component makers. Whatever Apple puts out, is the same as the competition is putting out, and what you'll find inside any of those ultrabooks is a lot more powerful than the technology of 4 years ago that could be found in the Mac Airs.
Now, can you name any of those ultrabooks makers that are putting 4 year old technology inside of those computers? Can you name any ultrabook which has a processor that is less powerful than whatever Apple puts inside their current offerings?
It's okay being an Apple fanatic, but why not try being a bit more honest with your comments?
