Im with you on that one Kolla, never liked datatypes and always removed them from my set ups, there are much better apps for viewing files/pics etc.. on the miggy. 
I don't follow the logic here, that I prefer to open apps first and then load files into them has nothing to do with datatypes. My comment was regarding "the default way how files where handled/opened on workbench", which again, has nothing to do with datatypes.
