While Lazarus/FPC is great, I do feel that Embarcadero can boost Delphi adoption if only they released the base/Community compiler for unrestricted use. I mean I don't know how feasible is that, and I am ok with whatever they wanna charge for their full fledged IDE or even their tools, but compiler could really help the situation. That's my only gripe with Embarcadero.
They don't based on CE version their market (CE version is 2 years old, may be more from regular release).
Everyone working in production with Delphi uses the paid versions—some use PRO, some use ENT (like me), and some use ARCH.
Many don't consistently update the release (you can see this from the requests in the forums and in the QP), but they still use the paid version, not the "free" one.
The paid versions offer the greatest availability of Delphi features, and I must honestly say that the maintenance cost in my market is easily justified.
