A VGA connector requires a monitor that supports VGA input. Of those, I can think of PC monitors--and I won't even touch this one--or a TV set that supports VGA, such as some (all?) of the Samsung.
You don't seem to be grasping the concept. If Revolution supports different resolutions via VGA then supporting different resolution via component is going to be a walk in the park.
Surely you see that this market is dreadfully small? And that given all these issues, web browsing functionality on a console, though "interesting", is not really practical in an overal market sense?
Nobody said internet surfing on a console will the best thing since sliced bread. However surfing using the DPD on Revolution will be as close as you're going to get to surfing using a mouse on a computer. Whether the market for internet surfing on a console will be small or not isn't the point. The point is Revolution will allow it and some people will take advantage of it. For those who don't see the need for it, well they don't have to use it. Very simple. Almost all cars have cigarette lighters, but do you have to use it? Does the use of that cigarette lighter need to become mainstream?
