Actually I DO know the half of it. I just didn't have the room to include it all.
Thanks for the positive comments. @Prototype: Next time read the column, the thrust of which was that the industry is changing thanks to Heavy Rain. And it is a good thing!
Point is, if you want to play on xbl you need the hard drive. Want to save your games? you need a hard drive. It should be included and isn't unless you spring for a higher model. Then the price equals and even exceeds the PS3 price. sorry but I want a complete system, not one I have to cobble together.
