Elegant is subjective. It's better to talk about things like specs, issues, OS support, etc, and let people decide on the aesthetics themselves. Arguing over which design is more pleasing on the eye (or elegant) adds nothing to the discussion.
The original post suggesting the X220 listed a bunch of specs that it had (and that the poster needed) that the MacBook Air didn't. A response of, "Disregard that the design sucks cocks," adds nothing to the discussion even if that it your personal opinion. If someone thinks that the external looks of the laptop are important, they are not going to just blindly make the purchase based a comment on HN without personally checking it out.
The more important discussions are things like:
* X is billed as (or looks to be in the surface) a replacement for Y, but once you get it out of the showroom you'll notice issues A, B and C.
* X looks really cheap on the surface, but in my experience it's extremely durable.
* X looks really good, but doesn't run Operating System Y.
* X looks like it runs Operating System Y, until you need to use feature/hardware component Z.
