X-Box Vs. Atari

My brother-in-law the other day brought home an Atari from Target and it has been the coolest game system I have played in a long while. I have been playing Pong and Asteroids and Centipede for last couple of days and it has been bliss. One button with a joystick is all I needed to be entertained by a game system. He got this Atari with 40+ built in games for only $20.00. That's B A Utiful (complements of Bruce Nolan). Now, what is up with the X-box 360. I figure I could buy like 35 or more Atari's for the price of one X-box. Yes there is the quality difference and stuff and I do appreciate graphic intensive games, but that is a large price tag. Plus, I am the video gamer type as long as it doesn't make me sick. I am just wondering who is Microsoft targeting with this expensive monstrosity. Cus it's not me. Does anyone own this X-Box yet?
