I loved it. Great works and no problems.
The Luna (still in development) OS works well and very fast. There's only one downside to it: you can't minimize windows, so you can't multitask. Switching between windows just doesn't work. Devs say: You don't need to minimize windows, just close them. I don't think that it is handy to close and reopen for example a office programme every time.
Elementary OS is a (simple) remaster of Ubuntu 12.04 (Precise Pangolin). Shouldn't that be mentioned on the Summary page?
Beautiful but a lot of issues to resolve. For instance conky disappears, windows cannot be clicked, totally freezes with only keyboard access etc.
