I'm staying focused on my recent theme of best and worst this week. This column is devoted to identifying the top 10 software programs that were either the most successful or the most innovative in the modern era of desktop computing (1976 to the present). All of my thoughts here are debatable and if anyone wants to post an alternate list (with a rationale) using my basic criteria I'd be interested, and I'll try to link to all of the ideas on my Web log at www.dvorak.org.
