 There were several frequently cited complaints - for example, lack of Symbian-OS-style code indenting, lack of an easy "find in files" facility, speed of import of Symbian OS build files (MMPs), and difficulties using on-device debugging.In addition, the much-anticipated Managed Build System did not work properly - rather than offering a true incremental build, it frequently deleted everything and started again.Otherwise the reception was warm - the development environment is preferred to CodeWarrior, the IDE is based on Java so there are some speed and memory concerns, the IDE is often slow and has a pretty big memory foot print, all trademarks of the Java environment.
