sure Lazarus is now big enough to turn into professionnal projects with solid and stable sources to compile such projects.
what is missing to my point of view is a skin engine with effects, to make applications attractive and amazing to the final clients. RAD studio have it, and you can choose from around 15 templates of skins PLUS an embeded tool to make your own easily with bitmaps resources and effects.
If such a skin engine bypassing the OSes Frames and Titles, arrives inside Lazarus one day, giving the final users and the programmers Total Freedom on the look and feel (avoiding by the way boredom on platforms), THEN Lazarus will definitively superseed Delphi, simply because it compiles true natives apps ON ITS OWN
one can say "i want operators" like in C++, an other "i want a garbage collector" like in C#, and a far cousin "I want a blue keyboard with pink flakes" THAT IS OF NO MATTER! to copy others! What Matters is to go ahead with what clients need the most, maybe also to invent new concepts not belonging to others!
"Dont give them what they want, give them what they need, thats not the same" or you are going to get lost
When I work on my Qt project with my Qt team do you really think we care about VisualStudio or .Net compatibility? even if Qt and VS are C++! We dont care "compatibility" we care A TOOL THAT WORKS FINE with Great Power! to achieve our businesses from A to Z and eventually make money (that is "Productivity"!)
Time to become a Big Boy, Dear Lazarus! You deserve it! you dont need to copy the others ... you need to Go Ahead! and perhaps being copied by others in a final glory
Thank You Lazarus/FPC team
