Just an aside, only a high-definition TV can take real advantage of ANY system
over 32-bits, so 64-bit systems are (at present) a bit of overkill, so MKII
and Atari Jaguar wouldn't be the incredible leap yet, since (as far as I know)
HDTV hasn't reached the marketplace...(at least, not for anything a college
student can afford!)...give it about 3 years, but by then, you could have a
combination PC/CDi/Game System/Hi-Def Montior, but I'm looking ahead...
Reality check over...
