I'm thinking of getting an iPhone, but the free one that is offered doesn't have "Siri" on it. Is that something I could live without? I'm a grandmother!! We are heading to Disney with my DS, DIL, and 2 grandkids. I want to put relative Disney apps on the iPhone. I have an iPad 2 which I love, but it's too big to lug around the parks! Thanks for any info. Currently I just have a regular cell phone with a little keyboard on it.
