As for wait times, well, if those are an issue, you're visiting at the wrong time!
Of interest is this part..."While Verizon Wireless customers will have exclusive access to an array of enhanced features, Disney and Verizon are also working to ensure that some mobile information such as dining locations, show times and locations will be available to all parks visitors, regardless of their wireless company."
If you're used to going to theme parks, you realize that waiting for an attraction is just one of those things you have to deal with. My cell phone stays in my room and OFF when we're on vacation unless we're in the car or have one of those days where we might be doing different/separate things. One last thing to worry about losing while you're on a ride, or people calling you, too.
If there's a strong correlation among Toyota Prius owners, it is that they skew toward Mac/iPod/iPhone versus PC. But Prius' MP3 hook-up is designed for PC-based music players. (iPods work, but they don't display the track information.) Go figure.
Just goes to show that these deals are not (always) made based on board member relationships or customer preferences. It's who pays the most money to close the deal.
