Hey all you gammer heads, couple questions for you all. Now bear with me, I am WAY behind the times when it comes to game consoles, I still have an orginal PlayStation! I've been considering geting a PS3 but don't understand what the differences are between the types available, different harddrive sizes? What does the harddrive size have to do with anything? Why does it have a harddrive? Looks like it has an internet connection too, whats up with that? Thanks in advance. PS, Anyone want to buy a classic PlayStation ? Only $399
