He's referring to the fact you have to pay $99.00 to distribute your apps on the App Store.
The IDE's on both OS's are irrelevant arguments. There are free versions of Visual Studio as well that work just as nice as the Professional editions. Those editions are for corporate enterprise architect roles etc.
If you think Visual studio express works as well as pro, or that pro and the like are only for corporate enterprise architects and e like. You've clearly never used visual studio pro. Profiling and x64 support are two trivial examples of what's missing, both of which are features included in the free Xcode.
I'm specifically speaking on my personal experience with Visual C++, in which x64 is much more important. Additionally I'm unsure if native interop can be done at all with Express editions, since there is a seperate Visual Studio Express for every language.
I'm certain .Net languages have other limitations using the Express editions.
> Profiling is solved by using ANTS profiler.
If we are expressing equivalency with every free non Microsoft product with the similar Visual Studio pro feature the whole Discussion is moot, because you'll be able to find a Mono or GCC, or some other tool that has the same feature checkpoint. But that doesn't change the fact that Visual Studio Express doesn't have profiling among other things.
And us corporate solution architects tend to use ArgoUML if we have to delve into that crud.
VS Express is actually pretty much fine for 90% of development work. If you are in a TDD environment, you don't even need the unit test stuff as NUnit ships with a GUI test runner.
