I personally prefer tabs, but as suggested in this article, I do a lot of open source work, and use git for that and my job and spaces seem to win for both. So I use spaces. Also, amusingly, when IBM hired me (in the US), my contract listed my salary as $x per month. I'd seen it before from recruiters for jobs in London and such, but I don't think I'd ever seen it put that way in the states before.
