Pc of course has more capabilities. In almost every way the PC will beat any home console. I prefer a PS2 myself. A PC can get very costly in investing for games. Some games require a certain joystick and that joystick can only be played on certain games. There are also upgrades you have to worry about or you will suffer extreme lag.It's all the little things that add up for a negative game expierence for on the PC. However the negatives arent as bad as i may have mad them sound.
pc is very cool and nothing can compare to it yet...but in 2004 psx comes out, you can download music from the internet onto a cd, record tv shows on it, and much more. psp(playstation pocket) comes out soon in a few years to. If you buy the psx for an upgrade in graphics, dont. Its kind of a beefed up ps2 and doesnt have better graphics.
