Both Eclipse and Visual Studio are so much easier to use than XCode, and there are a lot of applications on iphone that requires you to use drag and drop. In C# I can build something really fast and show that off, but I am still having a hard time doing that on iphone.

Objective C is not a language thats easy to learn, such as Java or C#, even for a senior developer it still requires some adoption time.

Thats just my 2 cent
