Delphi is a very good product and will be around for years. It has a solid footing in corporate development. Yes, I am biased. I worked for Borland for many years and was a Certified Borland Delphi Client Server Developer and a Senior Developer Support Engineer for the Dephi product. If you search Amazon for "Chaim Krause", you will also find a book in which I was a co-author on Delphi.
Anders built Delphi. The same Anders that moved to Microsoft and built C#. You can think of it as taking the lessons learned while building Delphi and doing it all over again with C instead of PASCAL. From what I have heard, if you grok Delphi at the deepest level, the switch to C# is without pain.
Delphi makes an excellent first language. PASCAL was created for the purpose of instruction in computer science and Delphi makes is object oriented. It also has solid database support.
Although most of my programming these days is in Java, PHP, or Python, I still have a soft spot for Delphi.
