Even flash disks are pretty cheap these days. Moreover, many statically
linked programmes are often smaller (see dietlibc).

Dynamically linked programmes have some relocation overhead. I don't know
the actual performance decrease but it should be some percent (however
modern processor are optimised for this, so no comparison would be fair).

It was meant serious.
