Free RAM is available to be used, but you're not using it (yet). The 'real' free RAM is the sum of free + inactive (which is RAM that was being used, but currently is not). See this link for a description of the relevant terms:
Note that 4 GB is a lot of RAm, relatively speaking. My max is 2 GB, and even running several apps, including running Windows in a virtual machine (via Parallels), I still have >500 MB free. The Mac OS is very good at memory management.
