Thats right off the point entirely, so you admit that it is far far more slick/bug free on launch than any other smartphone? It certainly isnt taken as given that a closed system is stable - look at all the WM/Symbian OS's with zero extra software installed they just havent been that stable a) at launch b) even with updates.
You are defending the undefendable, like I have said lots of times this is great, it will force the current OS makers to get their acts together and will be all the more better for us.
No I really dont like the lack of 3rd party apps, and that is a big flaw in the iphone, it certainly isnt perfect, I will never profess to that.
