I hear what you say re: emulation, I emulate the NES on my PC.
I am thinking more along the line of letting my youngest have it hooked up in bedroom as my PC is off limits unless it is being monitored and controlled by me.
That's said, it would need to be a very keen price tag in order to warrant a purchase.
What I have owned to date.
Sinclair ZX spectrum, Atari 2600, Commodore 64, Atari ST, Amiga 500, Sega Master system, NES, SNES, Sega Mega drive, Playstation 1, Playstation 2, Gamecube, Playstation 3
What I am emulating,
KEGA, MAME, Nestopia, Mupen ++, PJ64, 1964, NullDC, DEMUL, ePSXe, PCSX2, DeSmuMe.
