Hello.

I am not biased towards Delphi or FPC\L, if I am biased towards anything it is Pascal language in general ;-)

What I do like in FPC\Lazarus compared to Delphi:

IDE is faster and does not need the .NET crap!!
Crossplatform possibilities - does it require any comments? FPC + OpenGL + SDL is way to go!!!
If you discover a bug and report it, you will get a response (response not fix) in a matter of day or even hours. I've reported two bugs so far, and one has been solved in one day and the other in one week. I think it is very fast compared to Delphi in which some bug exists for years.

What I miss in FPC\Lazarus

The ability to see a mistake in your code in the time you made it. Delphi underlines erroneus code with red "line". (Altought this feature is sometimes buggy atleast in Delphi 2007)
The native debbuger. Delphi debugger is way better, and I doubt that the debugger for FPC will be ever released. However, I fully understand how complicated thing is to write one for crossplatform language. So it is on my big whish list but I accept the reality ;-)
