Very effective Wysiwyg RAD IDE tool for windows. Modern OO language with strongly typed variables. Very easy to understand and use can create a good applications in short time even for many platforms : Windows, macOS, iOS, Android.
Very changing and non coherent commercial policy :
1/ Prices are rising and rising and rising:
XE2 pro update price in 2011 : 500 euros with mobile dev. library.
XE10 pro update price in 2017 : 1730 euros without mobile dev. library.
2/ With "pro" licenc you don't have Client server database connectivity.
3/ Even with the new 'starte' free edition prices are not OK for beginners so 'No new blood '.
Just try the free starter edition so considere to by the pro & C/S option for the development because it is a complete IDE and easy to use for targeting Windows, mobile dev Option for other plateforms.
