It sold about 102 million units. i think that can speak for itself. I like how it uses discs ( you can also burn the discs on your computer for free games), the importance of being on discs it can have much larger games, but you have to have it save it on something else such as a memory card. Its also nice to have a button to press to open the disc spot, so you don't have to have power to open it up. I like the fact that its a smaller system, but that makes me feel like I'm getting less. Graphics Quality I thought the graphics were quite nice, and that you can really tell this when you play games like medal of honor on here. Game Variety some of their better games are madden nfl 2000, medal of honor, and final fantasy 8, and this really shows that sony put a lot of effort into this console. Controller Comfort Well designed controller with well placed buttons. It was the first one of its time to have a controller like this, and the buttons were amazingly designed with your fingers not slipping off the buttons. Ease of Use Very simple and easy to use. Theres not much else I can say about this. Durability I can't really say how durable it is but I've taken care of mine (like a baby), and it still works.
