iPhones Everywhere

My wife was tied up with her business over the weekend and I spent Sunday chasing my daughter around Disneyland. When we weren't chasing Micky, my six year old budding Mac geek pointed out to me every iPhone she saw. Guess what? She saw a lot of iPhones! At one point we were sitting in a restaurant waiting for a seat and there were 8 people with their phones out. Five iPhones (not including mine which was in my pocket), two RIMs, and a Razr. Now I know this wasn't scientific by any stretch of the imagination but still it was telling that Apple got something right with the iPhone. Hopefully they'll continue to innovate with the platform and make it something worthy of such enthusiastic use. When is that SDK showing up again?
