Is it my hardware or is it software? (Look at memory.)

What are you asking?
I see nothing unusual, unless you don't have any applications loaded/running.

'free' says that there were almost all the RAM used. But desktop applett does not.
Swap is shown correctly.

Free displays the used ram including cached memory. This memory will be freed when needed.

Oh. Now I see. Thanks.
