The Amiga still owns the PC, Wii, PS3 and that overcooked turkey - the XBox360.
If you're talking about graphics then sure the latter stuff might be able to do fancy things and show more colours on screen but the Amiga stuff has originality, playability, floppy discs, no political correctness and a sense of tranquility and you can fit the whole Amiga back catalogue onto a DVD (probably)
There's also the fact the Amiga was about at a time where games were innocent and fluffy... none of this going round killing/maiming people. in a 3D environment. urgh.
Back then people popped pills in darkrooms like Pacman and didn't bother anyone
For me I painted myself blue and pretended to be Silly Putty.
