}Here, here!! Make sure you post what software you decide to copy protect

A case study: when Borland released the first update of the original
Sidekick (which had been copy protected), it offered a choice of
copy-protected for $50 and non-copy-protected for $80. Even though the
non-copy-protected version cost 60% more, it outsold the copy-protected
version by something like five to one!
