1. The development tool is too expensive. More than MS.
2. It is not easy to use. VB Write, a Windows Playing a Button, Double-click the Button pop-up dialog Hello World's programs including the editor automatically generated, only three lines:
Private submmand1_click ()
Msgbox "Hello, World!"
End Sub
Borland's development tools are not so simple in Delphi, CBuilder, and JBuilder is not so simple.
3. The upgrade is too frequent, causing the development tool to be unstable. A more famous INDY event is caused by the Unstable TCP library of VCL. VCL BUG is also too much.
4. Help is too bad. I remember that there is no search for the help of CBuilder / Delphi. The sample program in the help is not good, completely lower than the MSDN.
