It looks like caching. Free tells you exactly what you want to
know if you look at the line that starts with:
total used free shared buffers cached
Mem: 1572388 981856 590532 0 852032 18244
-/+ buffers/cache: 111580 1460808
Swap: 2097136 4 2097132
It says your system actually has 1460808KB available for applications.
I'd suggest you look at "man free".
