Most professionals use the IDE of their choice, not the one that might or might not be delivered with the language. I think PB has a good IDE but I prefer to have one IDE for all the languages I have to use, which is mostly C, C++, PB and Lua. In terms of rapid development, I think PB is right up there. So too in functions and features. Write a gui based app in PB and then write the same one in C......

If it sounds simple, you have not grasped the complexity.
My point was focused on PB vs Visual Basic / .NET (or Microsofts GUI form designer in general) which I am willing to bet a LOT of businesses use, even if its just for prototyping.
What would be really awesome is if we had a RAD IDE for ProGUI, once it hits the point where the majority of PrincieD's custom gadgets are done, etc..
I have tried the various Designers available for PB and just find them somewhat lacking, I suppose.. Especially in the code integration department, having to save independent files and then import them back into your project is a pain if you change something halfway.
But I would agree I find it quite easy and, so far, manageable to create GUIs from scratch in the main PB IDE.
