Any long-running system will have very little "free" memory. Free memory is wasted memory, so the OS finds some use for it.
The important part of the output of "free" in this context isn't how much is free, it's how much is cache vs how much is allocated to programs. Other os's have other ways of telling the same thing. Neither of those numbers generally has much to do with how much shows up in ps when large amounts of shared memory are in use.
