The following fifty proprietary programs are listed in no particular order 
within broad categories along with their open source alternatives. In some 
cases you could probably write your own book on frustrations with the 
proprietary programs shown here. In other cases, you'll discover that the 
open source alternative isn't quite up to snuff yet. And, in other cases

the open source advocate can replace those gems with equally shiny objects 
from the open source repertoire.
