Today is Delphi's 18th birthday. Delphi 1 started on February 14, 1995. I started to use it a little bit later and I'm still using it every day. I never regretted that decision.
In 1995, Delphi was an extraordinary development tool and it is still today an extraordinary one in its latest incarnation: Delphi XE3.
After 64 bits, Windows 8 and MAC OS X Lion, now Delphi goes mobile: http://www.embarcadero.com/products/delphi/ios-development
