I realize I'm a little biased in the world of smartphones. In the interest of full disclosure, I am a proud iPhone user. I love the apps, the ease of use, the large screen and the "bells and whistles."
In real estate, having a smartphone is not just an option but a necessity. Everyone wants a response right now, not later today.
So the question remains, can the iPhone still hold its lead in 2010 as the top smartphone in the United States?
