That's assuming that you have that option. I've worked at many places where there were no private offices (outside of the owner) and working remotely was greatly discouraged. From speaking with colleges, it's more common then it should be.
Heck, over the course of five jobs I've never been at a place where it wasn't open-plan with music playing. I've unfortunately needed to acquire a collection of earplugs and headphones to defend against the noise.
I have seen one place with private offices (albeit for higher-ranking management), and that was at Yahoo! Everywhere else had management on the benches with the rest of the team.
Maybe it's a cultural thing around here in Sydney.
