O n my non-SSD mini, before the change to SSD, I often had the experience you mention. Since then, no. But likely the behavior is still the same, just that the SSD manages it better.
Before SSD, I had to run "purge" in a terminal to get the memory back. I'll try starting lots of apps and see what happens on the new mini/SSD. Would be nice if Apple, finally, learns to handle swap space better.
