I just picked up an iPhone today. I was on the fence and even though I use a Macbook Pro (that I just picked up in the last 9 months), I have been reluctant to jump on the iPhone bandwagon.
What I like about the iPhone is that from a business point of view, I can easily sync iCal, iTunes, and lots of other things. There has been a huge amount of support coming from the app community for Droid based phones, but it's still not there.
For me, I didn't need the fastest phone in the world. I just wanted a phone that I knew would work. With Verizon's network, and the strong OS on the iPhone, I am all set.
