I have D5, D7 and D2005 on the same machine. The registry entries for *.dpr, *.pas, *.dfm and so on are set to one of them - D2005 I think since that was the last one I installed.
But mostly I use D7, which is my favorite. When I want to launch a DN, I right click on the *.dpr file and a list of options pops up which includes "open with.." as a submenu. Left clicking again on the one I want at that moment chooses the DN I want to use. So the registry entries don't affect me in any way other than that I have to right click and choose before launching. Alternatively, all DN are on the "Start|All Programs" menu sequence, so I can get to any of them that way, and use "File|Open Project.." once some DN has been launched to get going. So I don't find registry entries to be a problem at all, not even an inconvenience, and unless Borland marketing got in the act, I would expect the Turbo line to follow the same design lines.
