hehe I knew Benskywalker would waltz on in here..
I on the other hand, think that resolution is just as important as the millions of polygons you can pump. using his example of DVD's, you watch it on TV, then you watch it on your monitor. what do you see? graphics that look much better IMHO, you can see soo much more, but that requires even more processing power to fool people with high res devices into thinking it's real (the whole reason for Special effects).
So, IMHO, consoles suck for that reason. even they don't REALLY run at 640X480 on NTSC (I don't know about PAL), it's more like 512X whatever.. I don't remember
that's one part of the reason why your monitor @ 640X480 looks soo much better then your TV, the other reason is that TV updates the WHOLE screen every 1/30th of a second, but fools your eyes a bit by scanning every second line, each time it passes, so half the screen is refreshed every 1/60th of a second.
This allows more fluid motion, but loses on quality quite a bit. I'm a reolution fanatic, and here Benskywalker is a polygon fanatic! no wonder we don't agree on some things.
But he knows his stuff, and if the XBox is capable of going to HDTV (when will that ever become more realistic in terms of cost??) that will negate the point a fair amount. in fact, the highest res the HDTV is capable of (1920X1024 I think) is higher then most monitors can (1600X1200).
BTW, I just read in the latest Popular Science that the Xbox graphics chip will be running at 300mhz.. who know's if that's true, we'll see. I already saw some preliminary info on the Xbox, who know's if that's true too...
