hehe. I think the n64 has a few advanteges too, like when you're traveling, you can't bring a computer (unless it's a laptop, and laptops don't let you play most good games), and the n64 can be hooked up to someone's tv if they let you.
Computers i think are better though. You can upgrade them, get demos for free, games are cheaper (mario 64 for $40 makes me sick especially to see racer, which is expansion pack and rumble pak compatible drop to a beautiful $10!!!), you can get more out of the computer games too, since you can hack them and make your own levels.
