Comparison of GIS software

A reader who probably enjoys my bashing of Wikipedia sent me an interesting take on the GIS software packages. I’m guessing the person who created the table didn’t have much time to research the system requirements of all the different GIS software packages. Mapserver does run on Windows (I wouldn’t say it “runs” on the web, but then again I’m an ESRI apologist I guess) and “ESRI” does run on GNU/Linux (sorta as I believe only RHEL is supported) and one could say that ArcWeb runs on “the Web”. Don’t get me wrong, the task is very hard, but if you don’t know then don’t put “no” down. Someone care to bail this page out for the sake of GIS Day? Maybe Wikipedia User:Redlands can correct “ESRI”.
