This is a great write-up that shows what is important in a phone. It's how you interact with it, not the features, not the specs, it's how you use it.
I tend to agree with that. With both the G1 and the iPhone, the interaction with the device for the most part, has not been on the phone. It's been twitter, web, reading, music, and the smoothness of those two devices is unbeatable.
I hope that more phone manufacturers realize this and they start to build up their networks of apps. The app store with Apple, and integration with a PC to allow me to manage things either on the PC or the phone, it's unbeatable. If I could have read books from Barnes and Noble or Amazon on my G1, I might not have moved to an iPhone, but I couldn't and that mattered.
I'm not sure how big a deal it is for everyone else, but I see more and more people doing things on their phones that aren't involving making calls.
People building SQL Server apps, especially BI apps ought to consider these markets and look to build small applications that ensure a smooth interaction with customers. As much as I like browser apps onthe desktop, they don't work on a cell phone, even one with as large a screen as the iPhone of G1.
