I completely disagree. I think it looks like akward, linuxy, OSS style. Textmate and VIM with a proper theme/font looks much better.

I tried playing around with various Sublime themes and fonts, but I just find its fundamentally awkward looking, and its not just a matter of tweaking it.

This might seem like a silly requirement but I'm also a designer as well as a developer. It would be something that would bother me daily.
