It really is dependent upon your work environment, and the people you work for. When I started at my current job, we had two weeks vacation after 6 months, plus half a dozen holidays. We were a very young company, and I got the impression that policy was created somewhat arbitrarily when we only had a couple of full time employees.
We went to an 'unlimited' policy about 16 months ago, and one of our devs spent almost an entire month overseas earlier this year without issue. He's not too much of an outlier within our company in terms of how much vacation time is taken, either.
