It has pretty low entry barriers, and is pretty capable. When I used it (as a hobbiest, during Delphi 5 and Delphi 7 times), it had a superb tooling, and a really efficient compiler. Everything "just worked". It's now 15 - 20 years ago, when we created really tiny Windows exe files. A notepad.exe clone in only 23kb size - with no external dependencies at all, just using pure Windows32 API and Delphi. These where truely fun times.
Miss them some times.
