And ever since the introduction of iPhone, Apple has had additional millions of $99/year from iOS developers, yet the pace of improvement for Xcode, or even its documentation has gone worst, and not better.
I seriously hope they have something to show for in the coming WWDC.
Well, you need to buy an iPhone and a Mac only once every 5 years or so whereas the $99 fee is per annum. So this can be significant for someone who is scraping by on a low budget.
