Ask HN: Best web or Mac/Unix alternative to Excel?

I've made a full-time switch to Mac some time ago, but the only app that still makes me fire up Parallel Desktop is Excel. Word for Mac, Numbers, Google Docs are all really bad.. I need something that will let me easily create nice-looking lists, have the same formula syntax (only the basics) and keyboard shortcuts that I'm so used to. Is there anything like that out there?
