IFFFF I get one, I'm getting the WiFi one. I already have an iPhone, so AT&T's 3G service is nothing to brag about, especially when trying to load full pages. Not gonna shell out an extra what, $120 for the unit and $15 a month. No thanks.
I'm probably gonna wait until I see the new iPhone before deciding.
I think a lot of you are short sided here. Its not what it will do April 3 when its released, its what it will do after the developers get a hold of it. Think 3-5 years in the future. I will not get the first release. I will let them work the kinks out, shrink the price, up the memory and then enjoy what I believe will be a really great device.
