It is like some sort of OCD. They get hung up on details while failing to see the big picture.
that's it exactly... I can't tell you how many wise people in the world of GT have said exactly that.
However, I would point out that this GPS integration thingy has been in production for years and only is reportedly now being implemented. That couldn't have been one of their highest priorities compared to other stuff, if it took so long and is a "peripheral" type of feature.
Along with each iteration of GT, comes some new "edge" technology as they call it. After many GT's have come and gone, they will have completely bridged the gap between real and virtual. Baby steps, of course.
On the larger point, though, I agree that PD doesn't see the forest through the trees on many issues.
