Based on this ranking Delphi is going up in popularity, usually its ranked in 10th and 9th, but in the last months is going up.
I think it's time for those abandom Classic VB to move to Delphi where backwards compatibility matters!!.
Oh thinking about that, i found this interesting guide about migrating Visual Source Safe projects to StarTeam. A good option if you get the Architect / Enterprise version of Delphi that includes a StarTeam license.
