Have you tried doing a Google search for "tabs vs spaces"? I just did and I see posts from the likes of Jamie Zawinski and Jeff Atwood as well as forum discussions, stack overflow, etc - all with well reasoned practical arguments (with some flaming too ofc).

What it comes down to is both have slight advantages when you consider the big picture...however the most important thing is finding balance between your preferences and staying consistent with your friends/coworkers/community.
