Personal systems I've owned:
Pong-------The original. Connected to the TV and all it did was play Pong. Not sure it qualifies as a "system", but it was awesome at the time (late 70's, early 80's).
Nintendo Entertainment System--8 bit.
Sega's handheld (Gamegear I think it was)
My son has a Game Boy Advanced. He's 7, so he's still pretty new to the whole game system market.
Yes doctor, I am sick.
Sick of those who are spineless.
Sick of those who feel self-entitled.
Sick of those who are hypocrites.
Yes doctor, an army is forming.
Yes doctor, there will be a war.
Yes doctor, there will be blood.....
