I liked Runtime Revolution. I wish the broader coding community would taken environments like this more seriously, is the text editor sacred? I left the platform before they added more mobile+online support, I'll have to see what they have added recently.
Livecode is great for creating tools on most platforms very fast. Literally a few hours to create quite functional frontends to commandline applications for instance. The batteries included way of working is breath of fresh air compared to what other environments have, but the reach of the platform seems limited. Mostly because to make applications actually release ready for ‘the world’ takes insane amounts of effort. However that does not diminish the power of the system for me; being able to whip up prototypes and ‘good enough’ helper/tool applications is something I only know from Tcl/Tk (especially with Visual tcl). Delphi/VB are fast but not as fast as these. I create mostly write-only software with it but for what I need it for, it is good and I do not know anything that matches that kind of productivity.
