I've been writing professional software for 30 years. A Delphi app that I released in the mid-90's is still the longest-running, most entrenched, still in-use application of anything else I did in that era. It amazes me that people are still using this little application and I still get heaps of praise for having written it, almost 30 years ago. People are still using it .. a testimony to just how well Delphi works and how powerfully useful apps can be made with it. I only wish I still had the sources for the app so I could try a Lazarus build an maybe fix a few bugs ..
