3 - One interesting more direct console related excerpt

"In the following image, we're going to zoom in a bit on one part of the image, so you can compare what it looks like without AA to the same view with 2x multisample AA applied. On modern graphics cards, this is the fastest, lowest-quality setting there is. On the Xbox 360, many claim that this level of AA is "free" and suffers no performance hit. Nothing is "free" in 3D graphics, but the performance penalty is probably quite small, thanks to the way the 360's graphics chip and embedded DRAM module work."

They do not talk about PS3 and Wii anti-aliasing, maybe because they do this in a more common way. But all explanation is a must read to anybody that wants talk about graphics effects knowing more than only the specifications launched with the console of choice.

4 - This was wht so many games looked better on the Dreamcast than on the PS2.

I'm only teasing here, but this is true:

When Dreamcast owners made fun of the PS2 for not having anti-aliasing, Sony said it wasn't important.

Make of that what you will.

4.3 - HDMI isn't important for the 360

If your TV supports it, it will do 1080 over VGA.

HDMI serves no purpose except for taking up an input on the TV (for the 360)

But at least Microsoft gives you a cable to use it with.

The main difference is that the Elite came out because people asked for it. Microsoft listened.
