First of all that story is unbelievable. But I can see why a 15 yr old might do that. Would any 15 yr old ask their parents for a vibrator? I don't think many would do that. She probably wanted to experiment and didn't have anything else.

Now to the systems.
The PS2 does have a leap with regards to software and developers. But it is a year older than the other two. So Nintendo and Microsoft had time to tweak their systems to be better than the PS2.
Nintendo, out of all the years they have made consoles, has never went with the crowd. Do you remember when the N64 came out? It was cartidge based. They should have went to cd but with their "wise minds" did not. Now it is the game cube with 3" discs and no hard drive or DVD playback, unless u shell out $400 to get the Panasonic gamecube from Japan. I just see Nintendo's next system, if there is one, with the componets from today's Xbox and PS2.
