The answer to your question is that "buffers" and "cached" reflect temporary usage of 'spare' memory. A rough idea of how much memory is unallocated is free + buffers + cached - free is just sitting there totally unused - buffers is something to do with storage space for data going to a block device (?) anyway it is temporary allocation that can be kicked to free up the memory - cached is recently seen data from a block device that is kept around in case it is needed again... it's totally lose-able to get the memory free again if it is needed for something else. -Andy
