Yeah, I love my Xbox 360. It's awesome. The only problem I can see parents having a fit with is the connotation that Xbox is only for fighters/shooters/other violent games when in reality it isn't, but a lot of parents don't even bother looking into that. That's why I think the Kinect is really going to help them out a lot. Nothing as cool as it and appeals to all ages.
I know. It would be awesome it we could. :p Bit of a shame that Nintendo likes to keep production costs low in order to make a profit, unlike Sony where you're virtually stealing from them because of how expensive hardware is. (Portable PS2.5 for £250 says hi.)
The 3G service could probably be on a pay as you go basis, where you buzz the 3DS into a newsagent and put money on it. You then use the money to buy packages for data transmissions and time using the service. You can also create e-mails and text messages on it. 3G turns off when a Internet hotspot is available.
That's just my Idea on how 3G could work on the 3DS.
Yeah I have to say that I wish the 3DS had it. Do you know if Nintendo has any plans for that? I'd have to see the price though, as the 3G service will probably not be cheap. I'd love to see that capability, though. That's one thing I think Nintendo is falling behind it. But then again, Nintendo also caters to a younger audience and kids aren't the ones paying for their products most of the time.
