Jim McKeeth has made a great blogpost, showing the extensive development, evolution and usage growth Delphi has been thru during the last 9 years, which the Tiobe index do not reflect.

Make sure to share this blogpost everywhere around, to make sure people take notice that Delphi is very much alive and well, and the absolutely easiest to use, development tool for creating bleeding edge, modern single source, multiple platform single and multiple tier applications.
I would personally not use Delphi, if it was not because Delphi is such a pleasure to program in. Focus on the functionality and UI, compile, test and debug in unsurpassed speed and be ready to deliver your well tested, speedy and low resource use, creation to your endusers.
Having developed with many other languages, including all the buzzword ones, I always find Delphi the tool that actually introduces enjoyment while developing.
Who have said that programming should not be enjoyable? It absolutely should!
