It always blows my mind that someone (a philanthropist or the government) hasn't just thrown down a few million bucks to make a truly user friendly version of LaTeX. The amount of grad student and professor time wasted dealing with the flaws in LaTeX is mind-boggling.

Or am I naive in this cost estimate? Does anyone know roughly how much money and developer time went into the currently best editors, like TeXShop and TeXnicCenter?
