I voted "I've got a few different systems." because I have my PS2 and my PC.
For the most part my oldest isn't ready for video games yet, she's only 5. My other girl is 2 1/2 and doesn't know what shes doing, but she likes to try. They play educational games (Blues Clues, Dora, Nick Jr's site) on the PC and the 5 year old also plays on "doll dressup" sites. I have no problems with video games as long as it doesn't take over your life in any way. As in, I won't go GTA on the freeway.
The scary thing is, the 5 yr old just asked me the other night when she could have a computer for her desk
