Pangaea

While reading about the farallon plate, I keep bumping into the
supercontinent Pangaea. While I've heard of this before, in various places,
I never really thought about it.

Something bothers me about this concept, and perhaps its my own
misinterpretation of the data, but to me the idea of Pangaea seems a little
too pat. The concept as I understand it is that roughly 200 million years
ago there existed a super continent from which all the current land masses
have originated. The theory seems plausible enough, the outlines of the
existing continents do match very well and also the relative motion of the
land masses does track well back to a single point of origin - but still.
The entire surface of the earth originated from a single bump on the crust
that slowly spread out over time?

Am I making too much of Pangaea in that the land was spread out before its
formation but by chance it collided together at that point in time?
Did Pangaea form as a single spurt of magma that broke the surface from some
mechanism (please don't invoke EE!!) and then slowly broke apart through
techtonics?
Is there insufficient data to extrapolate before the formation of Pangaea?
I've read something about terranes and zircons and it seems to lean toward
there being insufficient data. But I guess I wanted a more educated
opinion.
